1. Use the coordinate axes below to sketch a graph of a function y = f (.13) that satises the following properties (no work need be shown for this problem): (a) f(:r) is decreasing on (foo, 72) (b) f(:r:) is increasing on (2, 00). (c) f(:r) is concave up on (00, 1). ((1) x) is concave down on (1, 00). ('3) f(0) = 1
