Given the following functions:

f(x)=x^2

g(x)=x−3

Find the composition of the two functions and show your process:

f(g(x))

Answers

Answer:

[tex]x^2-6x+9[/tex]

Step-by-step explanation:

Say you have a function [tex]f(x)=x+1[/tex]. If you wanted to find f(3), you would replace the number in the parentheses, in this case 3, with x, to get [tex]f(3)=3+1=4.[/tex] When combining functions, you should do the same thing.

Here, we have [tex]f(x)=x^2.[/tex] We want to find f(g(x)). So, you should replace x in the function f(x) with the function g(x). [tex]g(x)=x-3.[/tex] So, f(g(x)) would equal [tex](x-3)^2[/tex], which equals [tex]x^2-6x+9[/tex].

C = total rental cost, m = # of miles you drive, w = # of week you rent

Place #1
C = $10 per week * number weeks + $0.29 per mile * number of miles
C = 10w + 0.29m

Place #2
C = $0.35 per mile * number of miles
C = 0.35m

You’re told you’ll rent it for 3 week, so m=3.

Place #1: C = 10*3 + 0.10m

Both agencies “charge the same” means the costs are the same. So set the two equations equal and solve for m.

A polynomial is
if its only factors over the integers are 1 and itself.

Answers

Answer: Prime

A polynomial is  prime    if its only factors over the integers are 1 and itself.

==============================================================

Explanation:

Think of the idea of factoring whole numbers like factoring 36 into 6*6 which further breaks down into (2*3)*(2*3) = 2^2*3^2. This shows that 36 is composite and not prime.

Something like 7 is prime because the only factors are 1 and itself.

This idea extends into polynomials as well.

Something like x^2+4x+4 factors to (x+2)(x+2) which shows it is not prime. On the other hand, the polynomial x^2+3x+5 is prime over the integers because we cannot factor it like the previous example. The only factors here are 1 and itself.

Factoring is handy to help determine roots of a polynomial. However, other tricks could be used such as the quadratic formula or using numerical approximation techniques.

If a = 5 and b=2 then find the value of - 2ab and - 3a+b

Answers

-2ab = -2(5)(2) = -20
-3a+b = -3(5)+2 = -13

Answer:

-2ab = -20-3a + b = -13

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

The volume of a crate with length of x feet, width of 8 - x feet, and a height of x - 3 feet is given by V(x)=x(8−x)(x−3) find the maximum volume of the crate and the dimensions for this volume

Answers

First, we need to find the maximum volume. In order to do this, we will first look at the dimensions of x and 8-x in the equation for volume. We can see that as x increases, so does 8-x. This means that there is a positive correlation between them. This also tells us that as x continues to increase, there will be a point where 8-x will equal 0. The maximum volume will occur when 8-x equals 0.

Therefore, the dimensions for the maximum volume are x=8 and x=-3.

Now we can solve for the actual maximum volume:

V max =(8)(8)-(3)(8)=64.

The maximum volume is 64 cubic feet and the dimensions for this volume are 8x=-3

Given that g(x)= 2x^2 - 3x + 19, find each of the following. A.) g(0) B.) G (-1) C.) g(3) D.)g(-x) E.) G (1-t)

Answers

Answer:

Given:

g(x)= 2x² - 3x + 19

Evaluate each value:

A)

g(0) = 2(0)² - 3(0) + 19 = 19

B)

g(-1) = 2(-1)² - 3(-1) + 19 = 2 + 3 + 19 = 24

C)

g(3) = 2(3)² - 3(3) + 19 = 18 - 9 + 19 = 28

D)

g(-x) = 2(-x)² - 3(-x) + 19 = 2x² + 3x + 19

E)

g(1 - t) = 2(1 - t)² - 3(1 - t) + 19 = 2(1 - 2t + t²) - 3 + 3t + 19 = 2t² - 4t + 2 + 3t + 16 = 2t² - t + 18

The entries for Row 3 in step 3 are : 0, -1, -2, 1

R_{1} = Row1

R_{3} = Row  3

Evaluate the function f(x)=x^2+6x+2 at the given values of the independent variable and simplify.
a. f(-8)
b. f(x+2)
c. f(-x)

Answers

Answer:

a) 18

b)x^2+10x+18

c)x^2 -6x+2

Step-by-step explanation:

This is a case of plugging in the value into f(x).

a) f(-8)= -8^2 + 6(-8) +2

f(-8)= 64 + (-48) +2

f(-8)=64 + (-46)

f(-8)=18

b)  f(x+2)= (x+2)^2+6(x+2)+2

So here I'll take a break to explain what's going on, because x+2 is a binomial meaning two terms and it is being squared I have to multiply the whole thing by itself. Meaning: (x+2) x (x+2), this is also known as foiling!! and for the next part its distributing 6 into x and 2.

    f(x+2)= x^2+4x+4+6x+12+2

I'll reorder it

 f(x+2)= x^2+4x+6x+12+2+4

    f(x+2)= x^2+10x+18

c) f(-x)= -x^2+6(-x) +2

f(-x)= x^2 -6x+2
