HP Prime Graphing NW280AAABA Equation mode, Graphs that are harder match by tapping Respectively

Choose a general form by tapping the Level

button— , and so on—until the form you want is displayed. The keys available to you to manipulate the graph vary from level to level.

Equation mode	Tap	to move to
	equation mode. In
	equation mode, you use
	the cursor keys to move
	between parameters in
	the equation and change
	their values, observing
	the effect on the graph
	displayed. Press \or =to decrease or increase the
	value of the selected parameter. Press >or <to select
	another parameter. PressQto change the sign. You
	have four forms (or levels) of graph, and the keys available
	for manipulating the equation depend on the level chosen.
Test mode	Tap	to enter test
	mode. In Test mode you test
	your skill at matching an
	equation to the graph
	shown. Test mode is like
	equation mode in that you
	use the cursor keys to select
	and change the value of each parameter in the equation.
	The goal is to try to match the graph that is shown.
	The app displays the graph of a randomly chosen
	quadratic function. Tap the Level button to choose
	between one of four forms of quadratic equation. You can
	also choose graphs that are relatively easy to match or
	graphs that are harder match (by tapping			or
		respectively).
	Now press the cursor keys to select a parameter and set
	its value. When you are ready, tap		to see if you
	have correctly matched your equation to the given graph.
	Tap	to see the correct answer and tap		to
	exit Test mode.
