Y = x^2- 2x - 3 A parabola in the xy-plane is given by the
equation above. Which of the following
equivalent forms of the equation displays the
coordinates of the vertex of the parabola as
constants or coefficients?
A) y = (x − 1)2 – 4
B) y = (x - 1)2 – 2
C) y = (x – 3)(x + 1)
D) y + 3 = x(x + 2)

the correct answer is the second option

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the aswere is the one with all 8's and the second one is with the 10,8 and 6
