(0, 3), (1, 9), (2, 19), and (3, 33) are all points on the graph of a Quadratic function. Write the Quadratic equation that represents that function.

Find the value of tan theta if sin theta = 12/13 and theta is in quadrant 2

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

Is this a polynomial function? i need to know asap
