In this video I show you the graphical relationship that exists between y = f(x) and its inverse function y = f – 1(x).
Example (1)
Example in the video
If f(x) = x2 – 1, x ε ℝ, x ≥ 0 :
- Find the range of f(x).
- Find f – 1(x) and state the domain
Example (2)
Example in the video
If f(x) = (x+1)2, x ε ℝ, x ≤ -2:
- Find the range
- Find f – 1(x) and state the domain
