EL-9600/9400 shows absolute values with | | just as written on paper by using the
Equation editor. Use of the calculator allows various absolute value functions to be
graphed quickly and shows their characteristics in an easy-to-understand manner. The
Shift/Change feature of the EL-9600/9400 allows visual understanding of how graph
changes affect the form of absolute value functions.

y = |x| changes to y = |x-2|
Notice that the function h in
the standard form
y = a|x - h|+ k takes charge
of horizontal movement of
the graph.
y = |x|
y = |x|
Notice that the coefficient a
in the standard form
y = a |x - h| + k takes
charge of changing the slope.
Notes
y = 2|x|
y = - |x|
