7. Which of the quadratic functions has the widest graph?

A. y = –4x2

B. y = 0.3x2

C. y = -4/5x2

D. y = 1/3x2

    The polygon is dilated using the origin as the center of dilation to create a smaller polygon, the rule that can represent this is (x, y) → (0.9x, 0.9y)

     Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.

     Dilation is the increase or decrease in the size of a figure.

     If a point A(x, y) is dilated by a factor k, the new point is A'(kx, ky). If k > 1 it is an enlargement and if k < 1, it is a reduction.
