During the holiday season Andrew has to help his mother wrap the candy that she makes. The number of pieces that she can wrap (y) can be described as y = 73. Andrew takes a lot more breaks to eat pieces of the candy, so he wraps at a rate of y = 3x + 8.
At how many minutes (s) have Andrew and his mother wrapped the same number of candy pieces?
2 minutes
O 3 minutes
0 4 minutes
t
8 minutes

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
