Parent FunctionsWho’s Yo Momma?

Part I: In Pencil

Standard Cubic Function

1. As a group, fill in the chart for y=x3. 2. Individually, plot the points you found on one of your four graphs and connect the dots in a smooth

fashion.3. Check the graph you found by graphing it your calculator:

a. Go to y=¿b. Clear everythingc. To type in x3, type X, then ^, then 3d. Hit GRAPH. Make sure you are in standard zoom (go to ZOOM and hit 6).

4. If your graph matches the calculator, write Standard Cubic Function above your graph and y=x3 below your graph. If your graph doesn’t match the calculator, find your errors and fix them.

5. Let me know when everyone in your group is done.

Standard Square Root Function

Repeat Steps 1-5 for the graph of y=√x. The square root symbol can be found by pushing 2ND and then the x2 button.

Standard Absolute Value Function

Repeat Steps 1-5 for the graph of y=¿x∨¿. This time, you’ll need to decide what x values you want to use. Choose 3 negative values and 3 positive values.

The absolute value symbol can be found by going to MATH scrolling over to NUM (number) and selecting 1.

Standard Quadratic Function

Repeat Steps 1-5 for the graph of y=x2.

Part II: In Marker

1. As a group, choose your favorite graph.2. On the standard graph paper, make an x- and a y-axis and label your units (let every 2 squares be 1

unit).3. Plot the points you found and connect them.4. Copy the xy-chart you found onto Quadrant III.
