Answer:

(1)

[tex](f+g)(x)=3x^2+4x+7[/tex]

(2)


Step-by-step explanation:

we are given

[tex]f(x)=4x+7[/tex]

[tex]g(x)=3x^2[/tex]

we have to find (f+g)(x)

we can write

[tex](f+g)(x)=f(x)+g(x)[/tex]

now, we can plug values

and we get

[tex](f+g)(x)=4x+7+3x^2[/tex]

we can also write as

[tex](f+g)(x)=3x^2+4x+7[/tex]

so, answer is

[tex](f+g)(x)=3x^2+4x+7[/tex]
