The owner of a snow cone stand has determined that the cost C, in dollars, of operating the stand is approximately given by C(x)=x2-8x+5?
where x is the number of snow cones bought. Find the lowest cost to the nearest dollar.

As an accountant, you cannot have a negative cost to run a business (unless you are subsidized or are tricky like Tom Sawyer). Selling zero cones means the owner has a cost of $5. Did the problem (or teacher) mean Profit or Loss [ i e based on Sales ] ?? Then, at sales of 8, which involves expenses for employee wages, paper cones, ice, flavoring, and cart rental, the cost is still "only" $5. [imo the owner created a poor formula; or some operand signs are backwards.] Get clarification from your teacher.

C(x)= x² -8x +5 is a Quadratic Function
Use the first part of QF to solve for vertex x= -b/2a
x = -(-8)/2 = 4
c(4) = -11
