Answer:

B) 24

Step-by-step explanation:

f(x)=2x+4

g(x)=3x+1

----------------

g(3)=3(3)+1=9+1=10

f(g(3))=f(10)=2(10)+4=20+4=24

Composite functions are function into another function. The value of the composite function f(g(3)) is 24

Composite functions

Composite functions are function into another function. Given the following functions:

f (x) = 2x + 4 and;

g(x) = 3x + 1,

Determine the composite function f(g(3))

f(g(x)) = f(3x + 1)

f(3x+1) = 2(3x + 1) + 4

Substitute x = 3 into the result

f(g(3)) = 2(3(3)+1) + 4

f(g(3) = 2(10) + 4

f(g(3)) = 24

Hence the value of the composite function f(g(3)) is 24
