GRAPH

Notice that placing an h (>0) within the standard form

y = ax - h+ k will move the graph right h units on the x- axis.

Notice that adding a k (>0) within the standard form y=ax-h+kwill move the graph up k units on the y-axis.

The EL-9900 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.
