It means combining functions here is an example -> f (x) = 3x + 2 g(x) = 2x + 7
f (g (x) ) = f (2x + 7 )
= 3( 2x + 7 ) + 2
= 6x + 23
Combining functions is to create a new function that is based off of two or more other functions. You do this with the use of addition, subtraction, multiplication, and division.
