What is the correct answer of 1 3/5x8/10

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

Ihonestly have no clue if it's each or none.

|p| > 3 {-3, 3} {p|-3 < p < 3} {p|p < -3 or p > 3}
