Answer Key

1)  y = 0.04(5)x

2)  g(x) = 100(1/10)x

3)  h(x) = 2(1.5)x

4)  b(x) = 2(10)x

5)  b(x) = 1.2(0.5)

6)  p(t) = 210(0.4)

7)  D(r) = 1(6)x

8)  y = 64(0.75)

Tell whether the function represents exponential growth or exponential decay. Then graph the function.

Problem 1 :

f(x) = 2(1/3)x

Solution

Problem 2 :

f(x) = 4(3)x.

Solution

Problem 3 :

f(x) = (1/4)x

Solution

Problem 4 :

f(x) = (4/3)x

Solution

Problem 5 :

f(x) = 0.5(4)x

Solution

Problem 6 :

f(x) = 3(0.75)x

Solution

Problem 7 :

f(x) = 2(0.8)x

Solution

Problem 8 :

f(x) = 5(2)x

Solution
