Which equation is the inverse of y = 9x2 - 4?
x = 2√x +4
v
ivx+4
y=+ v +4
y +vx+4

The inverse will be:

Step-by-step explanation:

In order to find the inverse of the equation, we do a variable change, since we are finding the inverse, :

Now solve for y'.

First add 4 in both sides of the equation and change to the left y'.

= x + 4

Second divide by 9

/9 = (x + 4)/9

= (x + 4)/9

Now you will have to clear y, with the square root.

" alt="y'^{\frac{2}{2}} = \sqrt{x + 4} / \sqrt{9}" />" /> =

Simplifying terms

You can check the answer by doing the evaluation of the following equation:

(f o ) (x)

substitute the equation for y' or inverse function

f()

Now substitue the value into f(x)

You will have

=x

your answer is d 2,500
