Erick · Answer 1

If f (x) + g (x) = (f + g) (x), then we can simplify this by adding both functions together: ΙxΙ + 9 + ( - 6). This makes ΙxΙ + 3. The absolute value of x can only be something that is greater than or equal to zero for the function to make sense. This means your answer is a.) (f + g) (x) ≥ 3.
