An expression is shown below: 2x3y + 8xy − 4x2y − 16y
Part A: Rewrite the expression so that the GCF is factored completely.
Part B: Rewrite the expression completely factored. Show the steps of your work.

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
