1. graphs a polynomial function with the coefficients you give it. 2. I STRONGLY recommend you put this in turbo mode (shift + click the green flag) 3. Space to not clear your previous graphs 4. Typing "fill" will make all following coefficients 0 5. In the function ax^n + bx^n-1.... zx^0 you're first coefficient is a, the last is the z term. 6. A good example of a nice graph would be 3 coefficients with the first coefficient as 1 or (.0135) and the rest as 0
