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.

growth 19% increase

Step-by-step 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%.
