Annual profit in thousands of dollars is given by the function,p(x)=200square x3 +10,000,where x is the number of items sold in thousands, x less than 3.
describe the meaning of the numbers 3 and 10,000 in the formula.
find the profit for 5 different values of x.
graph the profit function over its given domain; use 5 values calculated in part 3 to construct the graph and connect these points with a smooth curve.
will this profit function have a maximum, if so what is it?

p(x)=0.5x+40x300 dollars,
how many items to be sold to get mazimun profit?
