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 + rb.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.
