Which of the following is a factor of f(x) = 3x3 + 8x2 − 87x + 28?

What is the logarithmic function modeled by the following table? x f(x) 9 2 27 3 81 4

Graph the system: f(x)= 3/x-2; f(x)= 1/2x + 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
