Maths log question please help- image attached
Answers
Answer:
a = 2 and b = -1.
Step-by-step explanation:
We want to show that the equation:
[tex]\displaystyle \log_{2} \left( y + 1\right) - 1 = 2\log_{2} x[/tex]
Can be rewritten as:
[tex]\displaystyle y = ax^2 + b[/tex]
Where a and b are integers.
Note that:
[tex]\displaystyle 1 = \log _{2} 2[/tex]
Hence:
[tex]\displaystyle \log_{2} \left( y + 1\right) - \log _2 2= 2\log_{2} x[/tex]
From logarithmic properties:
[tex]\displaystyle \log_2 \left(\frac{y+1}{2}\right) = 2\log_2 x[/tex]
Likewise:
[tex]\displaystyle \log_2 \left(\frac{y+1}{2}\right) = \log_2 x^2[/tex]
For the logs to be equivalent, the inner equations must be equivalent. Hence:
[tex]\displaystyle \frac{y+1}{2} = x^2[/tex]
Simplify:
[tex]\displaystyle y = 2x^2 - 1[/tex]
In conclusion, a = 2 and b = -1.

g(x)=
Write a relationship for a function whose g(x) values are 2 more than five times the principal square root of x.
Answers
Lets do
2 more than five times the square root of x[tex]\\ \sf\longmapsto g(x)=5\sqrt{x}+2[/tex]
Lets take an example
[tex]\\ \sf\longmapsto g(4)=5\sqrt{4}+2[/tex]
[tex]\\ \sf\longmapsto 5(2)+2[/tex]
[tex]\\ \sf\longmapsto 10+2[/tex]

“5 times” means “multiply by 5”.
The principal square root just means the regular square root.
Putting that together, you have
g(x) = 5 * sqrt(x) + 2

The functions f(x) = 2x and g(x) = 2-x+ 3 are combined using division to get function h(x).
Which represents the combined function?
Oh(x) = 22x + 3, x20
O h(x) = 22% -3, 20
Oh(x) = 22x + 3
X E all real numbers
Oh(x) = 22x – 3 x € all real numbers
Answers
Answer: the answer is not C
Step-by-step explanation:
The function that represents the combined function is h(x) = 2x/(2x + 3).
where x ∈ all real numbers.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = 2x
g(x) = 2x + 3
Now,
h(x) = f(x) / g(x)
h(x) = 2x / (2x + 3)
Where x ∈ all real numbers
Thus,
The combined function is h(x) = 2x / (2x + 3)

Pam needed to give her gardener the approximate square footage of her backyard. With each step being about 2 feet, Pam steps it off and counts 20 steps long and 40 steps wide. About how many square feet is the backyard?
Answers
Answer:
3,200 sq ft
Step-by-step explanation:
20 X 2ft = 40ft
40 X 2ft = 80ft
40ft X 80ft = 3,200 sq ft
The number of square feet in the backyard will be 3,200 square feet
Since each step is being about 2 feet, which means the length will be :
20 steps
Length=20×2
Length=40 feet
40 steps
Length=40×2
Length=80 feet
Now let calculate How many square feet is the backyard will
Square feet=40 feet×80 feet
Square feet=3,200 square feet
