1. Use Inverse Functions
Notes 7.5 (Day 2)

2. If you are looking for the inverse of f(x), it is written as f-1(x).
Inverse Functions
If given two functions f(x) and g(x), they are inverses if:
f(g(x)) = x, and g(f(x)) = x Or
f-1(x) = g(x) and g-1(x) = f(x)
Notation:
If you are looking for the inverse of f(x), it is written as f-1(x).

3. Show that the two functions are inverse functions.
f(g(x)) = x, and g(f(x)) = x

4. Show that the two functions are inverse functions.
f(g(x)) = x, and g(f(x)) = x

5. Show that the two functions are inverse functions.
f-1(x) = g(x) and g-1(x) = f(x)

6. Show that the two functions are inverse functions.
f-1(x) = g(x) and g-1(x) = f(x)
