Question

Find (f • g)(2) f(x)= 6x g(x)= 2x + 2 (f • g)(2)=

Answer 1

Explanation:

Another way to state the composition of functions is, in this case, f(g(2)). Which means we will evaluate the g function at an x value of 2, then take that solution and sub it into the f function for x.

g(2) = 2(2) + 2 and

g(2) = 6. Now take that and sub it into f for x:

f(6) = 6(6) and

f(6) = 36

f(g(2)) = 36
