Question

given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.

( y = 850(0.919)^x )

growth
decay
growth % increase
submit answer

Explanation:

Step1: Identify growth/decay factor

The base of the exponential term is $0.919$. Since $0 < 0.919 < 1$, this is decay.

Step2: Calculate decay percentage

Subtract the base from 1, convert to percentage:
$1 - 0.919 = 0.081 = 8.1\%$

Answer:

Decay, 8.1% decrease
