Given the functions:
f(x) = 8x - 6
g(x) = (x + 6)/8
The expression (g ∘ f)(x) means replacing the "x" value in the g(x) function with the f(x) value.
Therefore, we have:
[tex]\begin{gathered} g(x)=\frac{x+6}{8} \\ \text{Substitute x with f(x).} \\ g(x)=\frac{(8x-6)+6}{8} \\ \text{Simplify the function.} \\ g(x)=\frac{8x}{8} \\ g(x)=x \end{gathered}[/tex]
