How do I solve this problem

Question

If (3,6) is a point on the graph of y=f(x), what point must be on the graph of y=f(-x)? Explain.

Answer 1

If f(x) is an odd function then f(-x)=-f(x) then the point will be (-3,-6) however if f(x) is an even function then f(-x)=f(x) and the point will be (-3,6).

Ok?
