The equation of a circle with center (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2
A diameter of 18 means a radius of 9.
(x + 3)^2 + (y - 5)^2 = 81

When a graph is symmetric about the origin, it is an odd function (Ex: y=x³)
When a graph is symmetric about the y-axis, it is an even function (Ex: y=x²)
A function is considered even if f(x) = f(−x) and it is considered odd if f(-x)=-f(x).
