Do problems C, E and G only
Do problem B only
Determine the truth value of each expression below. The domain is the set of all real numbers. (a) vx3y (xy > 0) Solution False. If x = 0, there is no y such that xy > 0. (b) 3xvy (xy = 0) Solution True. If x = 0, then for all y, xy = 0 vxuyaz (z = (x-y)/3) vxayvz (-(-)/3) – Vy (xy= y) (1) 3xayaz (x2 + y = 24) Solution True. One example is x = 3, y = 4, z = 5. Vay y = x in yerixovy=x). Doc, e, g The domain for vanables x and y is a groun of people.
