Graphing calculators are valuable in middle school and high school algebra classes. In algebra, it's important to know how to graph equations and determine the values of equations for particular x-values. Your graphing calculator allows you to create a graph of an equation and to plug in various x-values and obtain the corresponding y-values. Graphing calculators can save you a significant amount of time on homework and exams.
Instructions
1. Type your equation into the Y= portion of your calculator. For example, if you'd like to find the graph of y=x3, plug x3 into your calculator.
2. Hit "graph", to obtain the graph for the equation.
3. Press "calc," then enter the value of x that you'd like to plug into your calculator. Press "enter." Your calculator will display the corresponding value of y.
