Graph the exponential function by using a table, and then identify its key characteristics. Be sure to show 4 accurate points (its okay if the graph is wobbly or not exact)

2

The Mendez family just bought a home for
$180,000. If the value of the home increases at a rate of 3% per year, use an exponential function to find the approximate
value of the home after 10 years.

Growth Formula:

Decay Formula:
A=P\left(1-r\right)^t
