⚠️ILL GIVE BRAINIEST, please answer with a full sentence or more. The graph of a quadratic relationship is in the shape of a parabola. Parabolas are symmetric arcs and are useful for modeling relationships such as the height of a projectile
over time or the curve of the cables on a suspension bridge. Think about where you have
seen a parabolic arc in real life. What unique features did it have, and where did you see
symmetry in the relationship?

I folded a chainring on my bike so instead of a circle it was more parabolic and it was semi symetric due to the amount of teeth on each side of it.

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
