Option C: $y=\pm\frac{\sqrt{x+4}}{3}$ is the inverse of the function

Explanation:

The given function is $y=9 x^{2}-4$

We need to determine the inverse of the function.

To determine the inverse of the function, we need to interchange the values of x and y and solve for y.

Let us interchange the variables x and y in the function $y=9 x^{2}-4$ , we have,

$x=9 y^{2}-4$

Adding both sides of the equation by 4, we have,

$x+4=9 y^{2}$

Dividing both sides of the equation by 9, we have,

$\frac{x+4}{9} =y^2$

Switch sides, we have,

$y^2=\frac{x+4}{9}$

Taking square root on both sides of the equation, we have,

$y=\pm\frac{\sqrt{x+4}}{3}$

Thus, the inverse of the function is $y=\pm\frac{\sqrt{x+4}}{3}$

Therefore, Option C is the correct answer.

Sean and his sister, Betty equally mow 8/9th the total area of a lawn. What fraction of the total area did each of them mow? (Sh

Alexxx [7]

Since they mowed $\frac{8}{9}$ of the lawn in two equal parts, we need to split the pieces that were mowed into two equal groups. We know that in total they mowed 8 out of the total 9 pieces of lawn, so two equal groups that make 8 would be of size 4, since $\frac{8}{2}=4$ . Then they each mowed $\frac{4}{9}$ of the lawn.
