plug in f(4) in the f(x) equation and whatever answer you get from that plug that in for the g(x) equation.

f(4)= 4

f(x)= 2x-4

= 2(4)-4

=8-4

f(4)=4

Answer:

f(4) = 4

Step-by-step explanation:

f(x) = 2x - 4  Plug in 4

f(4) = 2(4) - 4 Multiply 2 and 4

f(4) = 8 - 4 Subtract 4 from 8

f(4) = 4
