What is the equation in standard form of a parabola that contains the following points (-2, -,-,-20) a: y= -2.5x^2 + 5x b: y= -x^2 +4x-4 c y= -2x^2 +4x-4 d y= -2.25x^2 +4.5x -2

I  believe your answer is C) y = -2x^2 + 4x - 4

yes

step-by-step explanation:

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.
