1)_(10 pts) True or False? a) If f(a) = f(b) then a = b T F b) A vertical line intersects the graph of a function at most once T F c) If f is a function, then f (3x) = 3f (x) T F d) If f is a function, then f(a + b) = f(a) + f(b) T F e) If f is continuous at a, then f will differentiable at a T F f) If f and g are differentiable, then - If (x) g(x)] = f'(x) g'(x) T F
