Which of the following is false for an exponential growth function y = C(1 + r)t?
 when C > 0, the function decreases from left to right
 the function has a y-intercept of (0, C) 
 the graph of this function will be identical to the graph of y = abx, if a = c and b = 1 + r
 if C > 0 and r > 0, then the graph will only have positive y-values.
