Find the converse of each implication below. Determine the truth value of each implication and its converse. Justify your answers. When not specified otherwise, you may assume variables represent real numbers. (a). If m e Z then 2m +1 E Z. (b). (x 3) = (x+3) only if x = 0. (c). If |x +3| < 1 then x < 0. (d). If x2 = 9 then x = (e). x + T E Q only if x 4 Q. (f). If x2 = 1 then x = 1 or x = -1. = 3.
