The number of tickets sold each day for an upcoming performance of Handel's Messial is given by N(x)=-0.5x^2+13+12, where x is the number of days since the concert was first announced. When will daily ticket sales peak and how many tickets will be sold that day?

    max at \[-\frac{b}{2a}=-\frac{13}{2\times (-.5)}=13\]

    day thirteen is the most, and you sell whatever you get when you replace x by 13
