If the base b in an exponential function is greater than 1 b 1 then the function represents exponential growth. Its exponential decay when the base of our exponential is in between 1 and 0 and those numbers get smaller. Then it explains how to determine when a certain level of decay w.
For example in the case of radioactive decay the formula would look like this.
No there are vertical and other asymptotes as well. For many of you this would not say too much. Then it explains how to determine when a certain level of decay w. Exponential functions can also be applied in real world contexts to determine things like population growth and radioactive decay.
