Question

Help me please I don’t know what to do

Answer 1

If you want to find an inverse function, you switch the places of the x and the y coordinates and solve for the new y. If we switch the x and y in our function we have
`x=8 √(y)`. We now have to "undo" that square root by squaring both sides. Doing that gives us
`x^(2) =64y`. Dividing both sides by 64 gives us that
`y= (1)/(64) x^(2) ,x \geq 0`, the third choice down.
