(a) If ε = {s, p, I, e, n, d, o, u, r}, X= {s, p, e, n, d)
Y= s, e, n, 0, 1}
Z = {p, n, o, u, r}
Find X n (Y'UZ).
(b) Given that for sets A and B in a universal set E, ACB, find An(An B)'.

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

Consider the function f(x)=-5x+3 what is f(-2)
