y=41(0.6)^x

Question

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

y=41(0.6)^x

Is it growing or decreasing? and by what percent of increase or decrease?

Answer 1

This represents decay.  As the x values increase, the overall result is gettimg snaller.

 

 

When function is in the form of y = a(r)^x where  0 < r < 1, (in this instance, r = .6) this represents decay.
