Given:g(x)=5x1 and h(x)= x + 4 Find:g(h(x))

Answer 1

I think you mistyped g(x) since the 1 seems out of place. Let's assume g(x) = 5x+1

g(h(x)) just means to replace x in g(x) with h(x).

g(x) = 5x + 1

g(x) = 5(x) + 1

g(h(x)) = 5(h(x)) + 1

g(h(x)) = 5(x + 4) + 1

g(h(x)) = (5*x) + (5*4) + 1

g(h(x)) = 5x + 20 + 1

g(h(x)) = 5x + 21
