Aright rectangular prism is packed with cubes of side length fraction 1 over 3 inch. if the prism is packed with 6 cubes along the length, 4 cubes along the width, and 8 cubes along the height, what is the volume of the prism a) fraction 7 and 1 over 9 cubic inches b) fraction 17 and 7 over 9 cubic inches c) 16 cubic inches d) 192 cubic 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
