Question

Which equation can be simplified to find the inverse of y = x2 – 7?
x=y2-1/7
1/x=y2-7
x = y2 – 7
–x = y2 – 7

Answer 1

What do you think is the correct answer?

Answer 2

I did the inverse but I got a fraction @John_ES

Answer 3

Interesting, in order to get the inverse you obtain first an equation where the x and y are interchanged. In this case the correct option should be the third one.

Answer 4

so just switch when doing inverse ? @John_ES

Answer 5

Exactly, then, if you want to obtain the inverse, simply solve for y.
