The following image shows how to create the y-values for this equation in Excel using the range of 1 to 10 for the x-values. Open the program Microsoft Excel. Steps 1-7 show you how to evaluate a quadratic function using Excel and steps 8- allow you to graph a quadratic function from the data.
In cell A2 type -10.
Assuming the y-intercept is 0 a quadratic equation has the form. In cell A2 type -10. The values that are entered dont matter for now because well be adjusting them later to fit the function to the data. Plot a Quadratic Equation.
