Find the equation of the quadratic function with zeros -4 and 4 and vertex at (0, -16). y = x2 - 16 y = -x2 - 16 y = x2 16 y = -x2 16

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above

Which letters from the table represent like terms? a and b b and c a and d b and d

The mass of a marine organism, in pounds, p years after it is born is given by the polynomial function r(p) = -4p2 + 300p. find the mass when p = 20 years.
