If f(x) = (x + 9 and g(x) = --6, which describes the range of (f + g)(x)?
S_A_V [24]

Given:

Consider the below figure attached with this question.

To find:

The value of (f+g)(x).

Solution:

The given functions are:

f(x)=|x|+9

g(x)=-6

Now,

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

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

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

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

We know that,

|x|\geq 0

Adding 3 on both sides, we get

|x|+3\geq 0+3

(f+g)(x)\geq 3

So, (f+g)(x)\geq 3 for all values of x.

Hence, the correct option is A.
