What is a expression? What is a mathematical equation? What do you mean by domain and range of a function?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.
For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which [y] exists.
We have a graph of a function as shown in the image.
It can be seen that the points -
x = 4
x = - 2
x = - 4
x = - 6
are the values in the domain of the function as domain represents the set of values of [x] for which [y] exists.
Therefore, the values -
x = 4
x = - 2
x = - 4
x = - 6
are the values in the domain of the function

Find the distance from point A to the given line. Round to the nearest tenth.
A(-4,4), y = 0.8x - 0.4
Answer:
The parallel equation is y = 0.8x + 6.8
Step-by-step explanation:
The distance from point A(-4,4) from the line y = 0.8x -0.4 is 0.31215.
What is a distance of a point from the line?The shortest path between any two points on an infinite straight line is called the distance from a point to a line. The length of the line segment connecting the point to the closest point on the line is the perpendicular distance between the point and the line.
The given point is A(-4,4), and the equation of the line is y = 0.8x - 0.4. The distance of the point is calculated by the formula written below.
d = (Ax+By+C) / [√(A² + B²)]
The equation is,
y = 0.8x - 0.4
0.8x - y - 0.4 = 0
Ax+By+C
A = 0.8, B = -1 C = 0.4
Substitute the values and solve for distance,
d = (Ax+By+C) / [√(A² + B²)]
d = ({0.8x-4}+{-1x4)-0.4) / [√(0.8² + (-1)²)]
d = 0.4 / 1.25
d = 0.3125
Therefore, the distance from point A(-4,4) from the line y = 0.8x -0.4 is 0.31215.

Answer:
The graph of g(x) is the graph of f(x) translated 6 units down, and
g(x) = f(x) - 6
Step-by-step explanation:
Let us revise the vertical translated of a function f(x)
If f(x) translated k units up, then its image g(x) = f(x) + kIf f(x) translated k units down, then its image g(x) = f(x) - kThe form of the linear function is f(x) = m x + b, where
m is the slope of the lineb is the y-intercept (value y at x = 0)We will the rules above to solve the question
∵ f(x) = 3x + 1
→ Compare f(x) with the form of the function above
∴ m = 3 and b = 1
∴ The y-intercept is (0, 1)
∴ The graph of f(x) intersects the y-axis at point (0, 1)
From the graph
∵ The graph of g(x) intersects the y-axis at the point (0, -5)
→ That means the y-intercept of g(x) is down the y-intercept of f(x)
∵ The difference between the y-intercepts g(x) and f(x) = -5 - 1 = -6
∴ The graph of f(x) is moved down by 6 units
∴ The image of f(x) is g(x) = f(x) - 6
The graph of g(x) is the graph of f(x) translated 6 units down, and
g(x) = f(x) - 6
What is x when f(x)=0? -1.8 -1.2 0 5
Answer:
0
Step-by-step explanation:
Remember that f(x) stands for y. No number can be equal to 0 other than it self. Thus, proving that 0 is only logical answer.
f(x) = 0 → y = 0 → 0 = 0

Write the equation from the following graph in slope intercept form
Answer:
y= -2/3 x - 2
Step-by-step explanation:
The linear graph crosses the x-axis at {-3,0} and the y-axis at { 0,-2}
The slope of the line will be given by:
m=Δy/Δx
m=-2-0/0--3
m= -2/3
The equation will be given as :
m= Δy/Δx
-2/3 = y--2/ x-0
-2/3 = y+2/x-0
-2/3 = y+2 /x-0
y= -2/3 x - 2

After you add those number subtract 1,200
But what 6,000 plus 200 equal??
Answer:
200+200+1,000+6,000 = 7,400 - 1,200 = 6,200
6,000+200=6,200
Step-by-step explanation:
so 200 plus 200 equal to 400 plus 1,000 equal to 1,400 plus 6,000 equal to 7,400 and then 7,400 subtract by 1,200 equal to 6,200.

Answer:
I believe it is A
Step-by-step explanation:
When you subtract z1 from z2, you get 2-4i, which on the graph is point A.
Point A represents 2-4i in the graph given. Therefore, option (1) is the correct answer.
Given that, [tex]z_{1}=5-2i[/tex] and [tex]z_{2}=3+2i[/tex].
We need to find the value of [tex]z_{1}-z_{2}[/tex].

=2-4i
Here, 4i is the imaginary and 2 real numbers.
Point A represents 2-4i in the graph given. Therefore, option (1) is the correct answer.

Describe the graph of the function f(x) = x3 − 11x2 + 36x − 36. Include the y-intercept, x-intercepts, and the shape of the graph.
Please help!
Please note: This explanation may appear to be incomplete because Brainly software falsely accuses me of using swear words or a URL. I have deleted some of my answer to get Brainly to accept part of it.
The y-intercept is found by setting x = 0: f(0) = (0)^3 − 11(0)^2 + 36(0) − 36. We get f(0) = -36. The y-intercept is thus (0, -36).
The x-intercepts are found from the roots/zeros of x^3 − 11x^2 + 36x − 36.
Synthetic division is very helpful in finding the roots of polynomials. We list possible factors of the constant term -36 and test each in
x^3 − 11x^2 + 36x − 36 until we find one or more factors of -36 for which the remainder is zero. -36 has the possible factors ±1, ±2, ±3, ±4, ±6, ±12, ±18, ±36.
Let's try -4. Is this a root of x^3 − 11x^2 + 36x − 36?
-4 / 1 -11 36 -36
4 28 256
------------------------------ No, -4 is not a root of x^3 − 11x^2 + 36x − 36
1 -7 64 220 because the remainder is 220, not 0.
Eliminate the possibility x = -4. Continue in the same way, testing each possible factor of -36 as a zero remainder. Try x = 2. We get:
2 / 1 -11 36 -36
2 -18 36
---------------------------
1 -9 18 0 Since the remainder is 0, we know that 2
is a root of x^3 − 11x^2 + 36x − 36.
Similarly, test x = 3: Using the coefficients 1 -11 36 -36, we obtain a zero remainder and thus can conclude that 3 is a root or zero of the original equation.
Thus, the roots/zeros of the original equation are {2, 3, 6}
and the corresponding factors of this equation are thus
{(x - 2), (x - 3), (x - 6). The x-intercepts are {(0, 2), (0, 3), (0, 6)} This function has no negative root/roots. Thus, the entire graph lies to the right of the y-axis. The curve increases/rises between x = 0 and x = 2 and crosses the x-axis at (0, 2). Then it decreases/drops between x = 2 and x = 3. Finally, the curve increases/rises again to the right of x = 6, always increasing.

[tex]=-6x+7y=-6\times \dfrac{3}{4}+7\times \dfrac{5}{8}\\\\=-3\times \dfrac{3}{2}+\dfrac{35}{8}\\\\=\dfrac{-9}{2}+\dfrac{35}{8}\\\\=\dfrac{-1}{8}[/tex]

What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
A triangle labeled A B C. Side BC is the base, side AB is perpendicular, and side AC is the hypotenuse. Angle A is labeled x degrees, angle B is labeled 3x degrees, and angle C is labeled 2x degrees.
Then the equation is given as,
x + 2x + 3x = 180°

x = 30°
Then the measure of the angle ∠C is calculated as,
∠C = 2 × 30°
∠C = 60°
The value of the variable 'x' is 30°. Then the measure of the angle ∠C will be 60°.
