Lets find the equation that represents that relationship:
y = zx^2
plug in data:
18 = z(6)^2
18 = z(36)
z = 1/2
then the equation is:
y = (1/2)x^2
now you just have to plot that equation

Answer:
Step-by-step explanation:
A polygon in the plane has rotational symmetry if the figure can be mapped onto itself by rotating between 0 and 360° about it's center.
So, we need to find the number of symmetrical line a regular polygon can have.
Note : A regular polygon with n sides has n lines of symmetry and order of symmetry n.
Then, let n be number of symmetrical line lines
Then,
Smallest angle of rotation about the center for which the polygon will be mapped unto itself is
360 / n
