What is the decay rate of a substance?

Back

The decay rate of a substance is the percentage at which it decreases over a specific period of time. For example, a decay rate of 20% per hour means that 20% of the substance is lost every hour.

What does the term 'growth rate' mean in an exponential function?

Back

The growth rate in an exponential function indicates how much the quantity increases over time, expressed as a percentage. For example, a growth rate of 15% means the quantity increases by 15% each time period.

Front

What is the difference between exponential growth and exponential decay?

Back

Exponential growth occurs when a quantity increases over time, while exponential decay occurs when a quantity decreases over time. Growth is represented by a base greater than 1, and decay is represented by a base between 0 and 1.

Front

How can you determine if a function represents exponential growth or decay?

Back

You can determine if a function represents exponential growth or decay by examining the base of the exponential function. If the base is greater than 1, it represents growth; if the base is between 0 and 1, it represents decay.
