Question

16)
f(x)=x^2+5x
g(x)=4x
Find (fcirc g)(x)

Renato · Accepted Answer

To find (f \circ g)(x), we need to substitute g(x) into f(x). Given: f(x) = x^2 + 5x g(x) = 4x Substitute g(x) into f(x): (f \circ g)(x) = f(g(x)) = f(4x) Now, substitute 4x into f(x): (f \circ g)(x) = (4x)^2 + 5(4x) Simplify the expression: (f \circ g)(x) = 16x^2 + 20x Therefore, (f \circ g)(x) = 16x^2 + 20x.
