Question

Medal to whoever gives an acceptable, satisfying answer. When looking at a rational function f(x) = (x - 6)(x + 3)(x + 4) / (x + 6)(x - 3)(x - 4), Jamal and Angie have two different thoughts. Jamal says that the function is defined at x = –6, x = 3, and x = 4. Angie says that the function is undefined at those x values. Who is correct? Justify your reasoning.
