Q-2:
a) Let U = {x: x is an integer and 2 < x < 10}. In each of the following cases,
find A, B and determine whether A C B,B C A, both or neither:
i. А —
{x: 2x + 1> 7}, B = {x: x² > 20}.
ii. A = {x:x? – 3x + 2 = 0}, B = {x:x +7 is a perfect square}.
b) Which of the following functions, whose domain and codomain are the real
numbers, are one-to-one, which are onto, and which have inverses, justify
your answers:
i. f(x) = |x|.
ii. f(x) = x3 + 6.
