Jan 29, 2021 · It’s easiest to visually see even, odd, or neither when looking at a graph. Sometimes it’s difficult or impossible to graph a function, so there is an algebraic way to check as well. When we talk about “even, odd, or neither” we’re talking about the symmetry of a function.
Understand whether a function is even, odd, or neither with clear and friendly explanations, accompanied by illustrative examples for a comprehensive grasp of the concept.

A function is "even" when: f(x) = f(−x) for all x In other words there is symmetry about the y-axis(like a reflection): This is the curve f(x) = x2+1 They got called "even" functions because the functions x2, x4, x6, x8, etc behave like that, but there are other functions that behave like that too, such as cos(x): Cosine function: f(x) = cos(x) It ...
A function is "odd" when: −f(x) = f(−x) for all x Note the minus in front of f(x): −f(x). And we get origin symmetry: This is the curve f(x) = x3−x They got called "odd" because the functions x, x3, x5, x7, etc behave like that, but there are other functions that behave like that, too, such assin(x): Sine function: f(x) = sin(x) It is an odd functi...
Don't be misled by the names "odd" and "even" ... they are just names ... and a function does not have to beeven or odd. In fact most functions are neither odd nor even. For example, just adding 1 to the curve above gets this: This is the curve f(x) = x3−x+1 It is not an odd function, and it is not an even function either. It is neither odd nor eve...
Adding: 1. The sum of two even functions is even 2. The sum of two odd functions is odd 3. The sum of an even and odd function is neither even nor odd (unless one function is zero). Multiplying: 1. The product of two even functions is an even function. 2. The product of two odd functions is an even function. 3. The product of an even function and a...
Sep 9, 2024 · One way to classify functions is as either "even," "odd," or neither. These terms refer to the repetition or symmetry of the function. The best way to tell is to manipulate the function algebraically. You can also view the function's graph...

Dec 21, 2021 · Knowing whether a function is even or odd helps you to graph it because that information tells you which half of the points you have to graph. These types of functions are symmetrical, so whatever is on one side is exactly the same as the other side.

Given a graph of a function, to test whether it is even or odd, consider the symmetry of the graph. Recall that an even function is symmetric about the y-axis while an odd function is symmetric about the origin.
Without looking at a graph, we can determine whether the function is even or odd by finding formulas for the reflections and determining if they return us to the original function. Let’s begin with the rule for even functions.
