Question

F(x) = 4x + 7, g(x) = 3x2

Answer 1

Answer:

(1)

$(f+g)(x)=3x^2+4x+7$

(2)

Step-by-step explanation:

we are given

$f(x)=4x+7$

$g(x)=3x^2$

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

we can write

$(f+g)(x)=f(x)+g(x)$

now, we can plug values

and we get

$(f+g)(x)=4x+7+3x^2$

we can also write as

$(f+g)(x)=3x^2+4x+7$

so, answer is

$(f+g)(x)=3x^2+4x+7$
