Question

Which equation can be simplified to find the inverse of y = x2 - 7?

Answer 1

Answer:

The inverse is

$y = \pm \sqrt{ {x}^{2} - 7 }$

Step-by-step explanation:

The options are not provided.

However, I will show you how to find the inverse of

$y = {x}^{2} - 7$

We interchange x and y to get,

$x = {y}^{2} - 7$

We solve for y,

${y}^{2} = x + 7$

$y = \pm \sqrt{x + 7}$
