Answer:
Step-by-step explanation:
Given is a function
This function is a parabola with vertex at (2,0) and axis of symmetry is x=2
Hence for x<2 the curve would be reflection of x>2
To get inverse we must get one to one funciton only.
So restrict the domain of f(x) to
Then we have f(x) as one to one with domain x≥2 and range is R+
For this inverse domain is R+ and range is
