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