Achef boiled 4 eggs and put them in a basket with 8 eggs that were not boiled. all of the eggs look the same. randy selects an egg, keeps it, and then selects another egg. which expression gives the probability that he selects 2 boiled eggs?
a. 4/12*3/11
b. 4/12*4/12
c.4/12*3/12
d.4/12*4/11

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.
