Here is a problem we had, it confused the heck out of me. The quiz was on finding properties of graphs (min, max, vertex, roots.) and we are allowed to use graphing calc.
Here is the parts of the problem I remember:
Selling Jazz Band concert tickets, if their sales and profit is represented by the formula: (-1/400) x (x2-4800x), how many would they have to sell to reach the max profit? (the x2 means x squared)
This is so confusing! The graph is a LINE no matter how I resize the window and x/y min/max! so is the answer Infinity?
Any help appreciated
