A new trendy restaurant is growing exponentially. After being open for 11 months the restaurant was serving an average of 310 customers a day. By month 15, the restaurant was serving about 456 customers a day. Write an exponential function N(t) that models average number of customers, N after t months of being open. If necessary, round any values to four decimal places (do not round on intermediate steps). Write your answer in the form a(b)t.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
