y = ± √x + 3/7 is the answer 100% sure

Elle Cordova · Answer 2

Given,

Let, f (x) = y = 7x^2-3

For Inverse function interchange role of x and y.

y = 7x^2-3

or, x = 7y^2-3

or, x+3=7y^2

or, (x+3) / 7 = y^2

or, (x+3) / 7*y=y

or, (x+3) / 7y=y

Therefore, Inverse of function:

f^-1 = (x+3) / 7y
