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

Which expression is equivalent to 2x^2+7x+4?

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5
