Question

Which equation shown below represents the equation of the inverse of the quadratic function shown below?

f(x)=(x+2)2+3

Answer 1

I guess the equation should be written:
f(x)=(x+2)^2 +3
If so, replace x by y & vice versa .
The final result is y=[square root of (x-3)]-1

Answer 2

Is (x-2)/3 -3 a choice?
