Given:
There are two functions given in question as:
[tex]\begin{gathered} f(x)=4x+4 \\ g(x)=3x^2+2x \end{gathered}[/tex]
Required:
We need to find the (f+g)(6)
Explanation:
First of all we need to find the (f+g)(x)
[tex](f+g)(x)=4x+4+3x^2+2x=3x^2+6x+4[/tex]
now put x=6 to find (f+g)(6)
[tex](f+g)(6)=3(6)^2+6*6+4=148[/tex]
Final answer:
[tex](f+g)(6)=148[/tex]
