Question

F(x)=4x^2 and g(x)=x+1, find (f x g)(x)

Answer 1

option b

Explanation:

It is option b

Your answer is 4(x+1)²

Answer 2

B

Explanation:

Given functions:

• 
  `f(x)=4x^2`

• 
  `g(x)=x+1`

`(f \circ g)(x) & =f[g(x)]`

This means substitute the x of f(x) with the function g(x).

`\implies f[g(x)]=4(x+1)^2`
