Question

If f(x)=|x| + 9 and g(x) =-6 , which describes the value of (f+g)(x)

Answer 1

f + g)(x) = |x| + 3

Explanation:

Add the two functions together:

f(x) = |x| + 9

+g(x) = - 6

------------------------

f(x) + g(x) = |x| + 9 - 6

= |x| + 3

The label f(x) + g(x) can be rewritten as (f + g)(x).

Thus, f + g)(x) = |x| + 3

Answer 2

Explanation:

This has a very brief answer when you know what it means.

f(x) + g(x) = abs(x) + 9 - 6

f(x) + g(x) = abs(x) + 3
