Graph the quadratic functions y = -2x^2 and y = -2x^2 + 4 on a separate piece of paper. Using those graphs, compare and contrast the shape and position of the graphs. I know that since both functions are quadratic functions, they will both have a parabola shape.

    up four units that is what the +4 represents negative number means that the parabolas are concave down or opens down both have a scale factor of 2 that is what the 2 in front of x^2 represents

    Okay, so y = -2x^2 will be a parabola opening downward with a scale factor of two. While y = -2x^2 + 4 will have a parabola opening downward with a scale factor of two, raised four units?

    raised four units one should say "function was translated vertically up 4 units"
