Using Visual Formula

Use Visual Formula to implement a quadratic equation. Then use this equation to test different values for quadratic. Set up the quadratic equation using the standard form of a quadratic equation:

f (x) = ax2 + bx + c

Here is an equation you can use for practical purposes of implementation:

f (x) = 3x2 + 3x – 1

To implement this equation, use the upper equation composition area. Refer to Figure 9.14 and follow these steps:

  1. Click the Value menu item five times in succession and, with each click, position a field in the upper equation composition area. Position the first two fields in close proximity to each other, skip enough space to allow for a field and an operator, and then position the third and fourth fields in close ...
