The student will then have to take the function and type it into the graphing calculator. The student will then look at the graph and try to find the correct ice cream in the ice cream dish.

DIRECTIONS FOR USE: Complete the following worksheet by matching each ice cream graph with the correct ice cream cone function. You may use a graphing calculator. Once you have all the ice creams matched with an ice cream cone, fill in the worksheet by drawing the graph with the correct function. Once the graph is drawn, you will need to find the maximum or the minimum value of the graph. When you are finished, hand the worksheet in for extra credit on the next test.
