Final answer:
To find an expression for g given a function, substitute the expression into g. In this case, g(x) = 8(x + 5), which simplifies to g(x) = 8x + 40.
Step-by-step explanation:
To find an expression for g given the function f(x) = x + 5 and g(x) = 8x, we can substitute the expression for f(x) into g(x). This gives us:
g(x) = 8(x + 5)
Simplifying further:
g(x) = 8x + 40
Therefore, an expression for g(x) is 8x + 40.
