The number of tickets sold each day for an upcoming performance of​ Handel's Messiah is given by N= -0.4x^2+9.6x+14 ​, 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?

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
