Question

Please help Asap Let f(x) = x^2 and g(x) = 2x.

(Enter your answer using interval notation.)

f ∘ g

Answer 1

f ∘ g = 4x²

Explanation:

Composite function:

A composition of functions f and g is given by:

`f \circ g(x) = f(g(x))`

In this question, we have that:

`f(x) = x^2, g(x) = 2x`

So the composite function is:

`f \circ g = f(g(x)) = f(2x) = (2x)^2 = 4x^2`

So

f ∘ g = 4x²
