Running to Conclusions (cont.)

Think about these questions.

- Can you use this graph to estimate what the world record was in the year 1500?
- How about forward to the year 3000?
- What are some of the reasons as to why or why not you could use this plot to answer the above questions?

It is reasonable for you to conclude that a straight line is not best way to predict future or past events using this data. However, lines and linear equations are not the only types of equations you know. Others such as polynomials, harmonic equations (sins and cosines) and exponential equations are other equations that can be used to fit data sets as well.

In the following lesson, you will explore a way to find an **exponential equation** to fit data sets.
