Question

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

a: x=y ^ 2 - 1/7
b: 1/x = y^2 - 7
c: x = y^2 – 7
d: –x = y^2 – 7

Answer 1

C- x=y^2-7

Explanation:

To find the inverse of the function you can just exchange the name of the variables, change x for y and y for x..

original (direct) function: y = x^2 - 7

inverse function x = y^2 - 7

Then, the answer is the option c.

Answer 2

To find the inverse of the function you can just exchange the name of the variables, change x for y and y for x..

original (direct) function: y = x^2 - 7

inverse function x = y^2 - 7

Then, the answer is the option c.
