Answer: x
Step-by-step explanation:
g(x) = 4x + 10 f(x) =[tex]\frac{x - 10}{4}[/tex]
to find g(f(x)), replace "x" in the g(x) equation with what f(x) equals. Another way of writing g(f(x)) for this problem is: g([tex]\frac{x - 10}{4}[/tex]).
g(f(x)) = 4[tex](\frac{x - 10}{4})[/tex] + 10
= x - 10 + 10
= x
