The box plots below show student grades on the most recent exam compared to overall grades in the class: two box plots shown. the top one is labeled class. minimum at 74, q1 at 78, median at 85, q3 at 93, maximum at 98. the bottom box plot is labeled exam. minimum at 81, q1 at 85, median at 93, q3 at 96, maximum at 99. which of the following best describes the information about the medians?

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.
