1. write a quadratic function, in standard form, that fits the set of points. solve it as a system of three equations (-4, 9), (0, -7), and (1, -1)

answer: 1 2 3 6

step-by-step explanation:

1x6=6 2x3=6

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
