Even number is a number that can be divided into two equal groups, as for odd number it cannot be divided into two equal groups.
To determine if function is even or odd you take the function and plug -x in for x, and then simplify. If u end up with the exact same function that you started with (that is, if f (-x) =f(x), so all of the signs are the same) then the function is even.
