Use the guide to construct a two column proof proving triangle AEC is congruent to triangle DEB, given that CA is parallel to DB and E is the midpoint of AD. Given:

The graph of f(x) is obtained by reflecting the graph of f(x)=-3|x| over the x-axis. which equation describes f(x)? a) f(x)=3|x| b) f(x)=|x+3| c) f(x)=-3|x| d) f(x) = - |x+3|
