imagine you are given for equations. The first equation is Blue Square + Green Circle = Red Square The second equation is Red Square X Green Circle = Blue Square X Blue Circle - Blue Circle The third equation is Blue Square + Blue Circle = Red Square + Red Circle + Red Circle The fourth equation is The square root of Red Square X Blue Circle - Red Square = ? Your answer choices are A-Green Circle, B-Blue Circle, C-Blue Square, and D-Red Square

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.
