Which equation is the inverse of y=2x^2-8

shusha [124]

Step-by-step explanation:

In order to get the inverse of equation, we will interchange the variables and solve for x and y as follows.

$y = 2x^{2} - 8$

whereas, $y + 8 = 2x^{2}$

or x = $\sqrt{\frac{y+8}{2}}$

Now, on interchanging the variable we will get the equation as follows.

$x = 2y^{2} - 8$

$x + 8 = 2y^{2}$

y = $\sqrt{\frac{x+8}{2}}$
