Question

Which equation can be simplified to find the inverse of y = 5x2+10?

A. x = 5y2 + 10
B. 1/y=5x^2+10
C. –y = 5x2 + 10
D. y= 1/5x^2+1/10

Answer 1

I agree, it's also A.

Answer 2

To find the inverse of a function, simply switch y with x:

So, y = 5x2 + 10 will become x = 5y2 + 10.

The correct option will therefore be A.
