Question

SO CONFUSED.

Given the following exponential function, identify whether the change represents
growth or decay, and determine the percentage rate of increase or decrease.
y = 980(1.5)

Answer 1

growth; 50%

Explanation:

growth because b>1

1.5>1

Using the formula for exponential functions, subtract 1.

1.5 - 1 = 0.5

To find percentage, multiply by 100.

0.5 x 100 = 50%

Answer 2

Growth by 50%

Explanation:

Growth, because it is higher than 1 and the percentage rate is 50% increasing.

Because growth is (1 +r) decay is (1-r).
