See how well you understand function expressions by trying to match your
function graph to a generated graph. Choose from several function types
or select random and let the computer choose.
Choose the type of function you would like to match. Random (Any) will choose among all possible types. Random
under each class will only choose a type among that class. Once you
start a problem it will be noted with a question mark. Completed
problems will be noted with a check mark.
On your graph, you can move the graph by clicking on the empty
space and dragging. You can also trace your graph by dragging along the
curve. This will show the coordinates of the point you are on.
Zoom In/Out changes the zoom of your graph.
In the bottom area, enter the values to match the generated graph
to your graph. Your function expression is corrected when the graphs
match. You can use the arrows to increase and decrease your values or
type them in directly with the keyboard.
Check checks to see if all your values are correct.
Hint reveals one value.
Reset All resets all function values of all types. It does not give you new problems.
Reset resets the function values of the current type. It does not give you a new problem.
New gives you a new problem of the current type.
Change Type is only active for random types. It allows you to change the type selected for your problem.
