Answer:
The inverse function is g(x) = ± , x ≥ -12 ⇒ D
Step-by-step explanation:
* Lets explain how to find the inverse function
- The steps of find the inverse of function f(x)
# Write y = f(x)
# Switch x and y
# Solve to find the new y
* Lets solve the problem
∵ f(x) = 9x² - 12
- Do the steps above
- Put y = f(x)
∵ y = f(x)
∴ y = 9x² - 12
- Switch x and y
∴ x = 9y² - 12
- Add both sides by 12
∴ x + 12 = 9y²
- take √ for both side don't forget to put ± in-front of it
∴ ± = 3y
- Divide both sides by 3
∴ y = ±
∵ There is no square root for negative number
∴ x + 12 ≥ 0 ⇒ subtract 12 from both sides
∴ x ≥ -12
- The function is defined for all values of x greater than or equal -12
∴ The inverse function is g(x) = ± , x ≥ -12
Answer:
Step-by-step explanation:
From the question we are told that
Sides difference
Area difference
Let first square be A
Let second square be B
Generally the area of a square is mathematically given by
Area of a square
Area of a square
Therefore from the equations above
Therefore
Side of the first square
Side of the second square.

Answer:
x= -1 is the another zero of the given function.
Step-by-step explanation:
We have been given a function:
The zero of the function is that point where the function vanishes or the value of the function becomes zero.
From the given four values we will put the values in the function and wherever we get zero is the zero of the function.
put x= -1 we get:
Hence, x= -1 is the another zero of the given function.
