Question 9 A graphic designer is creating a torso for a new cartoon character she is designing which is shaped using the quadratic function given
f(x) = -2x^2 - 12x - 16
Which represents the function in vertex form by completing the square to reveal the higheſt point from which to draw the neck?
f (x) = –2(x + 3)2 + 2; y = 2
f(x) = -2(x + 3)2 – 25; y = -25
f(x) = –2(x + 3)2 + 9; y = 9
f(x) = –2(x + 3)2 – 7; y=-7

Which statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent? a. use the slope formula to prove the slopes of the opposite sides are the same. b. use the slope formula to prove the slopes of the opposite sides are opposite reciprocals. c. use the distance formula to prove the lengths of the opposite sides are the same. d. use the distance formula to prove the midpoints of the opposite sides are the same.
