Question

Y=8200(1.19)x given the exponential function, identify whether the change represents growth or decay, determine the percentage rate of increase or decrease.

Answer 1

Explanation:

Answer 2

• growth
• 19% increase

Explanation:

When the exponential term is (1+r)^x, the fractional rate of change is r. Here, we have 1.19^x, so ...

1 +r = 1.19

r = 0.19 = 19%

This is a positive value, so the change represents growth at a rate of increase of 19%.
