Question

Which equation can be simplified to find the inverse of y=2x^2?

Answer 1

Answer:

$x=2 y^{2}$

Step-by-step explanation:

to get the inverse of

$y=2x^2$

we have to change its x by a y and its y by an x and then isolate the new y

$x=2y^{2} \\ \frac{x}{2} =y^{2} \\\ \sqrt{\frac{x}{2} } =y$

Answer 2

D) x = 2y^2, because you find the inverse by switching the x and y in the equation, so y = 2x^2 --> x = 2y^2
To simplify even further, you get
x/2 = 2y^2/2 --> y^2 = x/2
--> y = +/- sr(x/2)
