Answer:
g(2) = -13
f(g(2)) = -34
Explanation:
For g(2), just substitute 2 in for the x, multiply, and simplify.
g(x) = 5-9(x)
g(2) = 5-9(2) = 5-18 = <u>-13</u>
For f(g(2)), substitute this output in for x, multiply, and simplify.
f(x) = 5 + 3(x)
f(g(2)) = 5 + 3(g(2)) = 5 + 3(-13) = 5-39 = <u>-34</u>
Step-by-step explanation:
g(2)= 5-9(2)
= -13
f(g(2))= 5+3(-13)
= -34
