Functions Mathematics

INSTRUCTIONS ON HOW TO USE IT:
This Excel game is to be used in Math classes as a help-to-understand tool for the students. It contains several types of functions (y=ax; y=ax2+b; y=a log x +b, etc), one in each sheet. The user will be able to choose a value for “a” and “b”, and the function will be graphically represented, always contrasted with the basic function of its type (y=x, y=x2, y=log x, etc), so that the student has a graphic approach to mathematical analysis.INSTRUCTIONS ON HOW TO USE IT: This Excel game is to be used in Math classes as a help-to-understand tool for the students.
