Answer:
f ∘ g = 4x²
Step-by-step explanation:
Composite function:
A composition of functions f and g is given by:
[tex]f \circ g(x) = f(g(x))[/tex]
In this question, we have that:
[tex]f(x) = x^2, g(x) = 2x[/tex]
So the composite function is:
[tex]f \circ g = f(g(x)) = f(2x) = (2x)^2 = 4x^2[/tex]
So
f ∘ g = 4x²
