Solve the following equations. some equations will have a single answer, others will have no solution, and still others will have infinite solutions1. 2x + 2x + 2 = 4x + 2 2. 3(x − 1) = 2x + 9 3. 2x + 8 = 2(x + 4) 4. 2x − x + 7 = x + 3 + 4

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

Can someone me i’m confused. will give brainliest and a whole bunch of points
