Based on Tarek's diagram, how many
square inches of cardboard make up
his square pyramid?
te
A. 12 square inches
B. 35 square inches
C. 45 square inches
D. 54 square inches

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

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

x coordinate is none
