How do you identify an exponential function from a table of values?

Back

An exponential function can be identified if the ratio of consecutive outputs (y-values) is constant when the inputs (x-values) are increased by the same amount.

Front

What is the difference between linear and exponential functions?

Back

Linear functions have a constant rate of change, while exponential functions have a variable rate of change that increases or decreases multiplicatively.

Front

What does the base of an exponential function represent?

Back

The base of an exponential function indicates the growth factor. If the base is greater than 1, the function represents exponential growth; if it is between 0 and 1, it represents exponential decay.

Front

What does it mean if an exponential function has a base less than 1?

Back

If an exponential function has a base less than 1, it represents exponential decay, meaning the value of the function decreases as 'x' increases.
