It can be accessed by clicking on Wizard Button | Function | Subtract functions.
To subtract functions:
- Enter the first function.
- Press the
key or click on the next line. - Enter the second function.
- Press "Solve step" or "Solve all" button to see the solution process.
Make certain that you enter the function in functional notation. For example you can enter f(x)=2x+3. Also, use different names (letter designators) for different functions.
If you need an explanation for any particular step, click on the step and then click on the "Explain" button.
