Question

Point (-2,5) is found on f(x) and point (-2,-9) is found on g(x). On function (g-f)(x) describe one point we can be sure will exist.

Not sure hot to solve this because I don't have the equations?

Answer 1

(g-f)(-2) = g(-2) - f(-2) = -9 - 5 = -14

so, (-2,-14) will be on the graph of (g-f)(x)
