Use the functions [tex]f(x) = 2x^2 + 3[/tex] and [tex]g(x) = 3x - 4[/tex] to evaluate the composite function [tex]f(g(2))[/tex].

A. 62
B. 54
C. 48
D. 46

Answer :

Final answer:

To evaluate the composite function f(g(2)), substitute 2 into the function g(x) and then substitute the result into the function f(x). The value of f(g(2)) is 11.

Explanation:

To evaluate the composite function f(g(2)), we first substitute 2 into the function g(x):

g(2) = 3(2) - 4 = 6 - 4 = 2

Next, we substitute the result from g(2) into the function f(x):

f(g(2)) = f(2) = 2(2)^2 + 3 = 2(4) + 3 = 8 + 3 = 11

Therefore, the value of f(g(2)) is 11.
