Max is having a party for his four friends. He fills each gift bag with 3 candy bars and then divides the stickers equally among the bags. If there are a total of 32 items, which equation could be used to solve the problem? A. 4x + 3 = 32
B. 4x - 3 = 32
C. 3(x + 4) = 32
D. 4(x + 3) = 32

I believe it's B

Step-by-step explanation:

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
