Question

For the pair of functions, find the indicated composition.
- f(x)=4 x+15, g(x)=3 x-1 
Find $( f \circ g ) ( x )$
A)  12 x+44 
B)  12 x+11 
C)  12 x+14 
D)  12 x+19

Quizplus · Accepted Answer

To find $(f \circ g)(x)$, we substitute $g(x)$ into $f(x)$. So, $f(g(x)) = f(3x - 1) = 4(3x - 1) + 15 = 12x - 4 + 15 = 12x + 11$.
