Suppose f(x) = x2 - 2 - 12, g(x) = 2 + 3, andh(x) = 6x – 1. Which of the following function operations are correct? Select three that apply. A (f + g)(x) = 2 - 4
Os (f - h)(x) = 22 - 70 - 13
C(9* h)(x) = 6x2 + 17x - 3
D (g- h)(x) = 5x - 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

Alake near the arctic circle is covered by a 222-meter-thick sheet of ice during the cold winter months. when spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. after 333 weeks, the sheet is only 1.251.251, point, 25 meters thick. let s(t)s(t)s, left parenthesis, t, right parenthesis denote the ice sheet's thickness sss (measured in meters) as a function of time ttt (measured in weeks).
