Example: Piecewise functions

Here's how to author a sketch question related to piecewise functions:

NOTE: This example requires the student to graph lines and then use the snipping tools.

1. Enter this question statement in the Question Text pane of the Question Editor: Plot the piecewise function

1. Use the Equation Editor to define this function for the question statement:

1. Insert a Sketch response area and change only the following property:

• Group plots: Yes

1. Click Update to update the Sketch Board with your defined properties.

1. Define the correct answer in the following way:

• 5a. Use the Draw Line sketching tool to plot one line with the following points:
  • (0, 2) and (6, 0)
• 5b. Use the Draw Line sketching tool to plot a second line with the following points:
  • (-5, 0) and (0, -3)
• 5c. Use the Snip Left sketching tool and click on the point at (0, 2)
• 5d. Use the Snip Right sketching tool and click on the point at (0, -3)
• 5e. Use the Toggle Filled/Hollow sketching tool and click on the point at (0, -3)

1. Click Insert to insert the response area into your question.

1. The sketch response area is inserted into your question.

Example: Supply and demand

Here's how to author a sketch question related to supply and demand:

NOTE: This example requires the student to click-and-drag a curve and point on the Sketch Board.

1. Enter this question statement in the Question Text pane of the Question Editor: In the supply/demand graph below, demonstrate what will happen should the supply decrease by 15 at each price.

1. Insert a Sketch response area and change the following properties:

• Axes: 0, 50 ,0, 10
• Tickmarks: 5, 2, 5, 2

1. Click Update to update the Sketch Board with your defined properties.

1. Define the correct answer in the following way:

• 4a. Use the Draw Three-Point Parabola Segment sketching tool to plot one curve with the following points:
  • (5, 9), (30, 4), and (50, 2)
• 4b. Use the Switch Pre-Drawn sketching tool and select the curve you just plotted in 4a to make it a background curve
• 4c. Use the Draw Three-Point Parabola Segment sketching tool to plot a second curve with the following points:
  • (20, 2), (45, 7), and (50, 9)
• 4d. Use the Switch Pre-Drawn sketching tool and click-and-drag the curve you just plotted in 4c so that the curve now rests at the following points:
  • (5, 2), (30, 7), and (35, 9)
• 4e. Deselect the Switch Pre-Drawn sketching tool
• 4f. Use the Plot Dropline Point sketching tool to plot the following point (where the first two original curves from 4a and 4c overlap):
  • Approximately (33, 3.5)
• 4g. Use the Switch Pre-Drawn sketching tool and click-and-drag the point you just plotted in 4f so that the point now rests where the original curve and relocated curve overlap):
  • Approximately (24, 4.95)

TIP: Hovering your cursor over a plotted point reveals its plot coordinates to two decimal places to support you in the relocation of your plotted curves and points.

1. Click Insert to insert the response area into your question.

1. The sketch response area is inserted into your question.

Example: Transformations of functions

Here's how to author a sketch question related to transformations of functions:

NOTE: This example requires the student to use a background curve to reference for their plotted response.

1. Enter this question statement in the Question Text pane of the Question Editor: Given the graph of below​, graph ​.

1. Use the Equation Editor to define the two functions and insert them on either side of "below, graph" in the question statement from step 1:

1. Insert a Sketch response area and insert the following background function:

• Background functions: Math.pow(x+1,2)-3

NOTE: A background function is a pre-drawn curve that's defined using JavaScript syntax. Check out step 8 of the Author a sketch question help topic for more details on how to include a background function.

1. Click Update to update the Sketch Board with your defined properties.

1. Define the correct answer in the following way:

• Use the Draw Vertex-Point Parabola sketching tool to plot a curve line with the following points:
  • (-1, 3) and (0, 2)

1. Click Insert to insert the response area into your question.

1. The sketch response area is inserted into your question.

Example: Inequalities

Here's how to author a sketch question related to inequalities:

NOTE: This example requires the student to select a region on the Sketch Board.

1. Enter this question statement in the Question Text pane of the Question Editor: Graph the region that satisfies the inequalities and .

1. Use the Equation Editor to define two different inequalities and insert them on either side of "and" in the question statement from step 1:

1. Insert a Sketch response area using the default response area properties.

1. Define the correct answer in the following way:

• 4a. Use the Draw Line sketching tool to plot a line with the following points:
  • (0, 2) and (3, -2)
• 4b. Click the Toggle Solid/Dashed sketching tool and select the line you just plotted in 4a to make it dashed
•  4c. Use the Draw Line sketching tool to plot a second line with the following points:
  • (0, -3) and (3, -2)
• 4d. Click the Choose Region sketching tool and select the region created by the two lines that mostly overlays the negative x-axis
