Answer 1

F(x) domain = f-1(x) range
f(x) range = f-1(x) domain

Question 2

relationship between f(x) and f-1(x) gradient?

Answer 2

f-1(x) has the reciprocal gradient to f(x) at the same value of x.

Question 3

if f(x) passes through a point how to find the point f-1(x) passes through?

Answer 3
