Question

Please help me figure out how to solve this step by step as I’m very confused

Answer 1

Given:

There are two functions given in question as:

`\begin{gathered} f(x)=4x+4 \\ g(x)=3x^2+2x \end{gathered}`

Required:

We need to find the (f+g)(6)

Step-by-step explanation:

First of all we need to find the (f+g)(x)

`(f+g)(x)=4x+4+3x^2+2x=3x^2+6x+4`

now put x=6 to find (f+g)(6)

`(f+g)(6)=3(6)^2+6*6+4=148`

Final answer:

`(f+g)(6)=148`
