Depending on your skill level, this may be hard. Graph -3x^2 - 12x + 35 and find that maximum or minimum point(s) using either substitutions to approximate or derivatives depending on your skill level. Note that x^2 means x-squared. You can also do this function with higher orders if needed. x^3 + 3x^2 - 12x + 32 for example.
