You can tell if a function is even or odd by looking at its graph.
If a function has rotational symmetry about the origin (meaning it can be rotated 180 degrees about the origin and remain the same function) it is an odd function. f(-x)=-f(x) An example of an odd function is the parent sine function: y=sinx
If a function has symmetry about the y-axis (meaning it can be reflected across the y-axis to produce the same image) it is an even function. f(x)=f(-x) An example of an even function is the parent quadratic function: y=x2
An even function is symmetric about the y-axis. An odd function is anti-symmetric.
An even function is symmetric about the y-axis. If a function is symmetric about the origin, it is odd.

Neither.
It is difficult to tell what function you have in the question because the browser used by this site is hopelessly inadequate for mathematical notation.However,f(x) is an odd function of x if and only if f(-x) = -f(x) for all x.Common examples are f(x) = x^k where k is any odd integer, f(x) = sin(x).
To determine whether a given number is odd or even: function odd_even($i) { return ($i % 2 == 0 ? 'even' : 'odd'); }
A function f(x) is Even, if f(x) = f(-x) Odd, if f(x) = -f(-x)
Looking at the graph of the function can give you a good idea. However, to actually prove that it is even or odd may be more complicated. Using the definition of "even" and "odd", for an even function, you have to prove that f(x) = f(-x) for all values of "x"; and for an odd function, you have to prove that f(x) = -f(-x) for all values of "x".
An even function is a function that creates symmetry across the y-axis. An odd function is a function that creates origin symmetry.
I find it convenient to express other trigonometric functions in terms of sine and cosine - that tends to simplify things. The secant function is even because it is the reciprocal of the cosine function, which is even. The tangent function is the sine divided by the cosine - an odd function divided by an even function. Therefore it is odd. The cosecant is the reciprocal of an odd function, so it is naturally also an odd function.
An even function is symmetric about the y-axis. An odd function is anti-symmetric.
both
Yes. Along with the tangent function, sine is an odd function. Cosine, however, is an even function.
Yes f(x)=0 is both even and odd
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. A function can be either.
For an even function, f(-x) = f(x) for all x. For an odd function, f(-x) = -f(x) for all x.
You can't. Only whole numbers are odd or even.
