this is incorrect. find the x-coordinate for the vertex and plug it into the formula. the result for P(x) is the desired profit.

recall: For a quadratic , the x-coordinate of the vertex is given by:

again, you are way off here. BOTH roots are positive, so you did something wrong.b. determine the amount spent on advertising that will result in a profit. i keep gettin a negative number which i know cannot b rite.bt i am using the quadratic formula.

recall: for a quadratic , the roots of the quadratic are given by:

try again

are you sure you didn't mean to write 4000? because that is impossiblec. determine the amounts spent on advertising that will result in a profit of at least $4,000,000.00
