Question

F(x)=|3x+5|+6 g(x)=7 find (f+g) (x).

Answer 1

Answer:

$(f+g) (x)=\mid 3x+5\mid+13$

Step-by-step explanation:

Operation of Functions

Given:

$f(x)=\mid 3x+5\mid+6$

$g(x)=7$

The sum of (f+g) (x) is:

$(f+g) (x)=\mid 3x+5\mid+6+7$

We cannot operate with the expression inside the absolute bars, thus:

$\boxed{(f+g) (x)=\mid 3x+5\mid+13}$
