13. “Take g(x) and substitute f(x) in the place of x.”
Main 1:
composite functions
g(f(x))
“Take g(x) and substitute f(x) in the place of x.”

14. “Take g(x) and substitute f(x) in the place of x.”
Main 1:
composite functions
g(f(x))
“Take g(x) and substitute f(x) in the place of x.”
An example:
f(x)=2x-1
g(x)=5x
f(x)=2x-1
g(f(x))=5(2x-1)
