One of the most important uses of algebra is to model patterns of change. You are already familiar with linear patterns of change. Linear patterns have constant differences and straight-line graphs. In a linear relationship, the _y-value increases by a constant amount each time the x-value increases by 1.
In this unit, you will study exponential patterns of change. Exponential growth patterns are fascinating because, although the values may change gradually at first, they eventually increase very rapidly. Patterns that decrease, or decay, exponentially may decrease quickly at first, but eventually they decrease very slowly. As you work through the investigations in this unit, you will encounter problems like those the on the facing page.
