FIND EXPONENTIAL GROWTH OR DECAY RATE WORKSHEET

Rewrite the function to determine whether it represents exponential growth or exponential decay. Then find the percent of change.

Problem 1 :

y = 80(0.85)^2t

Problem 2 :

y = 67(1.13)^t/4

Problem 3 :

y = 5(3/2)^-8t

Problem 4 :

y = 17(2/5)^0.65t

Problem 5 :

y = 4(0.5)^t/88

Problem 6 :

y = 31(1.02)^4t

Problem 7 :

y = 9(1.12)^0.3t

Problem 8 :

y = 750(0.88)^t/3

Problem 9 :

y = (0.64)^5t

Problem 10 :

y = 6(0.82)^-0.25t
