Front

What is the decay factor if a substance decays at a rate of 20% per hour?

Back

The decay factor is 0.8, which means 80% of the substance remains after each hour.

Front

How do you determine the growth factor from a growth rate of 80%?

Back

The growth factor is calculated as 1 + growth rate = 1 + 0.8 = 1.8.

What is the difference between linear and exponential functions?

Back

Linear functions increase or decrease by a constant amount, while exponential functions increase or decrease by a constant percentage.
