After this lesson, you will be able to:

Our approach will be to: First we will plot the data using a TI graphing calculator. Once the data is entered, your screen should look like the following: After entering the data into the calculator, graph the data.

Your screen should look like the following: Next we want to find a quadratic equation that best fits the data we have plotted.

According to the calculator, the equation is the following: The graph of the function is the following: Based on the graph and the equation information listed above, it is clear that a quadratic is not a perfect function for representing this data.

Remember that a graph is a perfect fit for data when. However, based on the graph, our function is a fair fit for the given data. It would be better to have more data so that we could determine a graph having a better fit.
