How To Use A Graphing Calculator
How To Use A Graphing Calculator
Y= editor: enter equation to be graphed
• Equation must be in slope-intercept form
o [pic]
• Type in equation using letter key for x (located below mode)
o -or- use then hit appropriate letter
• To graph more than one line:
o Enter first equation into [pic] and second equation into [pic], etc.
• To change the type of the line to be graphed:
o Scroll to the left past [pic] and press enter
▪ Change to bold line, dotted line, and use to shade
GRAPH: creates graph of line
ZOOM: changes view of graph
• Zoom standard: looks at graph with intervals of 1
• Zoom In: pick a point by moving cursor to zoom in on area
WINDOW: changes intervals of x-axis and y-axis on graph
• Xmin: minimum value on x-axis
• Xmax: maximum value on x-axis
• Xscl: Interval of axis
• Same applies for y-axis
TRACE: allows you to find points on the line/graph and zoom in on point
• Move cursor to right or left to choose point
• Hit enter to zoom in on area with point
TABLE: allows you to see x-values and y-values in table format
• Use then graph to obtain table
TBLSET: Table Setup
• Use then format to obtain table set up
•
• TblStart: choose value of x you would like to start with in table
• [pic]Tbl: Change interval of x-values
• Input x-values to obtain y-values
[pic]
