Question

Choose the correct procedure for calculating (f + g)(-4) if f(x) = 2x + 1 and g(x) = x2 - 10.
Answer

Calculate f(-4) and g(-4), then add them together.

Calculate f(-4) and g(-4), then write the results as an ordered pair.

Calculate f(-4) and g(-4), then subtract them.

Calculate g(-4), plug the result into f(x) and simplify.

Answer 1

Calculate f(-4) and g(-4), then add them together.
or just add f to g and then substitute x=-4
