For the following exercises, identify whether the statement represents an exponential function. Explain.

For each training session, a personal trainer charges his clients $\$ 5$ less than the previous training session.

Hence, the statement is not exponential because the charge decreases by a constant amount each visit, so the statement represents a linear function.

so we can identify an exponential function. Because the rate of change is proportional to occurrence amounts. A linear function has a constant rate of change. The same amount is gained or lost in a time in this example, with fi decreases by the same amounts every session. So it is a linear function, not an exponential hands. Eventually, procession is just going to be free.
