Answer:

80x^2

Step-by-step explanation:

5x(4•2(2x))

5x(16x)

80x^2

Answer:

[tex]g(f(2x)) =80 x^2[/tex]

Step-by-step explanation:

If [tex]f(x)=4x^2[/tex], and [tex]g(x)=5x[/tex], then in order to find the composition [tex]g(f(2x))[/tex] we need to start by finding what [tex]f(2x)[/tex] is:

[tex]f(2x)=4(2x)^2=4*4x^2=16x^2[/tex]

[tex]g(f(2x)) = g(16x^2)= 5*(16x^2)=80 x^2[/tex]
