Answer:
A function with a graph that is symmetric about the origin is called an odd function. Note: A function can be neither even nor odd if it does not exhibit either symmetry. For example, f(x)=2x f ( x ) = 2 x is neither even nor odd
Step-by-step explanation:
Three times the square of a number means 
Nine times a number is 
If these quantities must be equal, we have

We can divide both sides by 3 to get

Since x is non-zero, we can divide both sides by x:
