Perform the requested operation or operations.

f(x) = x minus three divided by five.; g(x) = 5x + 3, find g(f(x)).

Respuesta :

[tex] f(x) = \frac{x-3}{5} [/tex]
[tex] g(x) = 5x+3 [/tex]
[tex] g(f(x)) = 5(\frac{x-3}{5})+3 = x-3+3 = x [/tex]

EDIT:
[tex]f(g(x))=\frac{(5x+3)-3}{5}=\frac{5x+0}{5}=\frac{5x}{5}=x[/tex]
