HeLp! While preparing for a morning conference, Mrs. Morvis is laying out 9 dozen bagels (1 dozen=12) on square plates. Each plate can hold 13 bagels.
How many plates of bagels will Mrs. Morvis have? How many more bagels will be needed to fill the final plate with bagels?
Mrs. Morvis will have plates and she will need bagels to fill the final plate.

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

answer: it's d
