# How to tell if a function is even or odd

Even functions are symmetrical about the y-axis: f(x)=f(-x). Odd functions are symmetrical about the x- and y-axis: f(x)=-f(-x). Let's use these definitions to determine if a function given as a table is even, odd, or neither. Learn how to determine if a function is even or odd. A function is even if the graph of the function is symmetrical about the y-axis, or a function is even if f(x) = f(-x). A function is odd if. We say that these graphs are symmetric about the origin. A function with a graph that is symmetric about the origin is called an odd function. Note: A function can be neither even nor odd if it does not exhibit either symmetry. How to Tell if a Function Is Even or Odd. 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. Even and Odd Functions. They are special types of functions. Even Functions. 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) = x 2 +1. They got called even functions because the functions x 2, x 4, x 6, x 8, etc behave like that, but there are other functions that behave like that too, such as. Purplemath. You may be asked to determine algebraically whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify.If you 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.If you end up with the exact opposite of what you started with (that. Some graphs exhibit symmetry. Graphs that have symmetry with respect to the y-axis are called even functions.Graphs the have symmetry with respect to the origin are called odd functions. Look at the graphs of the two functions f(x) = x 2 - 18 and g(x) = x 3 - 3x. The function f(x) = x 2 - 18 is symmetric with respect to the y-axis and is thus an even function. 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. If a function is even, the graph is […] How to Determine if a Function is Even, Odd or Neither I have prepared eight (8) worked examples to illustrate the procedure or steps on how to figure out if a given function is even, odd, or neither.
