The function g(x) is defined as shown. x-1, -2 g(x) = 2x+3, -1 6-x, x23

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 of the following is most likely the next step in the series? a3z, b6y, c9x, d12w, е15v, f18u
