Function Studio f (x) with x real variable.
Performs the study of the function in all its steps

1. Existence field
2. Intersection with Cartesian axes
3. Vertical asymptotes
4. Vertical and oblique asymptotes
5. First derived study (maximum and minimum)
6. Second derived study (flex) .
   The full function study can be invoked by the pull-down menu. The results box allows you to copy all of its contents that can then be exported to any word processor. It is possible to follow the function at any point thanks to the many zoom and pan activates both wisely (x or y axis) together. All the functions studied can be stored in a database and optionally recalled (visual help for recognizing the desired function) or permanently deleted from the database. All colors in the design field can be customized at will. You can then restore default colors with a click or touch.
   Help contains a list of primitive usable functions with some suggestions for good entry of functions.
   PS: To avoid errors the field that contains the function (above the graph) is read-only, so if you want to enter a new function you have to click Insert in the function menu, then write the function and click Validate to check for any errors will calculate the derivatives first and second and will show them to the right.
