1.	How to determine if a graph is even or odd?
Answer» If we substitute x with-x (negative x) in the function f(x) and the value of function f(x) becomes negative i.e.f(-x) = -f(x) for all x, then the function is known as odd function.If the value of function does not change i.e.f(-x) =f(x) for all x, then the function is known as an even function. We will use the concept of functions to find if the graph is even or odd.
