### Example Question #1 : Compare Function Properties: Ccss.Math.Content.Hsf If.C.9

The above table and figure describe two different particle's travel over time. Which particle has a larger maximum?

**Possible Answers:**

**Correct answer:**

This question is testing one's ability to compare the properties of functions when they are illustrated in different forms. This question specifically is asking for the examination and interpretation of two quadratic functions for which one is illustrated in a table format and the other is illustrated graphically.

For the purpose of Common Core Standards, "Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions)." falls within the Cluster C of "Analyze Functions Using Different Representations" concept (CCSS.MATH.CONTENT.HSF-IF.C.9).

Step 1: Identify the maximum of Table 1.

Using the table find the time value where the largest distance exists.

Now, let us plot the points from the table and connect them with a smooth curve to represent the function.

It is seen from the table and the graph that the vertex or maximum of the function exists at .

Step 2: Identify the maximum of Figure 2.

Looking at Figure 1, plotting the vertex and extending a vertical and horizontal line, we can find the coordinate pair of the vertex.

Therefore the vertex or maximum of Figure 1 is .

Step 3: Compare the maximums from step 1 and step 2.

Compare the value coordinate from both maximums.

Therefore, Figure 1 has the largest maximum.
