Suppose p(x) is a twicedifferentiable function such that p(1) = 3, p'(1) = 0, and p”(1) = 2. Which of the following is true?
there is a relative maximum at p(1) = 3
there is a relative minimum at p(1) = 3
there is a point of inflection at p(1) = 3
none of these are true

p'(1)=0 so max or min
p"(1) < 0, so concave down: a max
(A)
