## Tutorial for the MML Grapher

Some exercises in the Study Plan, Checkpoint, and Final Exam require the use of a graphing tool to enter
graphical answers. Using this tool, students can plot points, lines, absolute value functions,
parabolas, circles, 3-point quadratic functions, 4-point cubic functions, and transformation
graphs (including sine, cosine, exponential, and logarithmic functions). This information in this tutorial is *in addition to* the
help files in MML.

#### FINDING THE MML GRAPHER HELP FILES

Complete instructions for using the Grapher are found in the help file. Clicking on the "?" button on the Grapher toolbar
will take you directly to the MML Grapher Help file. As such, this "?" is the fastest way to find help on the MML Grapher:

You can also obtain more help using the MML Grapher through the MML help link:

In the help file, you will see a menu at the left of the screen. Click to expand the help book called "Answer questions in your player."
Next, click to expand the help book called "Enter answers in math courses."
Finally, click to expand the help book called "Use the grapher" as shown in the screen shot below.

#### TIPS & TRICKS NOT IN THE GRAPHER HELP FILES

**READ THE PROBLEM CAREFULLY:** Carefully read the instructions to the problem. If MML wants you to graph the line using slope and intercept, but you graph the line using both the x and y intercepts, even
though the line may be correct, MML will mark it wrong. In the
graph below, the problem asked you to graph using both the x and
y intercepts, but you use the y-intercept and the slope. As you
can see, the graph is exactly the same line, but because the
appropriate points weren't used, MML marked it wrong:

** GRAPHING FRACTIONAL & DECIMAL POINTS:**
It is possible to graph fractional and decimal points. First
graph the object with the points with non-decimal points close to
where you eventually want the fractional or decimal points.

To change a point to a fractional or decimal point, select the graphed object
with the selection tool (it will turn from a blue object to a
selected, orange object):

Select the desired point on the graph that you want to change into a fractional or decimal point
(a selected point will turn from a filled in [blue] point to a
not-filled in [clear] point). After selecting a point,
you will see the link to "Edit Coordinates" as shown by the
red arrow below. Click that link:

Enter the new coordinates:

** GRAPHING FRACTIONAL TRANSFORMATIONS:**
In order to graph a fractional transformation or base, first press
the slash mark (/) to get the fraction template:

** LOCATION OF YOUR CURSOR:**
As you are moving your cursor over the Grapher to create an
object, you will see the coordinates of your cursor (as shown by
the red arrow in the graphic below):

#### ENLARGING THE GRAPHER WINDOW

You can create graphs using the Grapher as it appears inside the problem viewer when the problem first loads. However, you can also enlarge the Grapher so that you can see your graph more clearly.
There are two ways to open the Grapher in an enlarged window: (1) Click on the magnifying glass icon in the upper right corner of the Grapher. The Grapher will open in a pop-up window. -or- (2) Click the large button at the bottom of the
question that says "Click to enlarge graph."

Drag the edges of this window to resize the Grapher, or click on the sizing tabs to make the graphing window larger.
I personally like working in Medium window because it's large enough for me to graph accurately, and yet I can still see the problem.

#### SELECTING A GRAPHER OBJECT

Click the selection tool:

Click your line/parabola/circle/etc. If your line is selected, the points you plotted will appear and the line will be orange:
