If f(x) = |x| + 9 and g(x) = –6, which describes the value of (f + g)(x)?
a.(f + g)(x) > 3 for all values of x
b.(f + g)(x) < 3 for all values of x
c.(f + g)(x) < 6 for all values of x
d.(f + g)(x) > 6 for all values of x

For this case we have the following functions:

We must find (f + g) (x):

By definition we have to:

So:

Thus, for every value of x the function will be positive and greater than or equal to 3.

If, the function is 3

Option A...
