Guided Notes
3 key concepts
- 1
Function composition involves nesting one function inside another to create a new function.
- 2
To evaluate F(G(2)), first find G(2), then use that result as the input for F.
- 3
In the example, H(G(F(2))) is evaluated by finding F(2) = 3, then G(3) = 4, and finally H(4) = -1.
