I HAVE TEST TO DO!!!

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

Graph y = -|x| + 2. click on the graph until the correct one appears.

Which shows the graph of the solution set of 3y – 2x > –18?
