I know this problem probably isn't as hard as I'm making it, but can someone help me with the problem, if anything, give some pointers to start me in the right direction?
+128475 W(x) constantly increases from left to right ....the slope is not constant and the point (0,1) is on the graph.....these are characteristics of an exponential
Z(x) is symmeric about x = 4......without knowing anything else, this seems to indicate a polynomial [ maybe a parabola ]
So....A seems to be the best choice
