 # Question: How Do You Tell If A Function Is Odd Even Or Neither?

## How do you determine if a piecewise function is even or odd?

f(x) = 1/x Here f(-x) = 1/(-x) = – 1/x = – f(x), so 1/x is an odd function.

f(x) is an EVEN function if and only if f(x) = f(-x) for all x in the domain of x.

f(x) is an ODD function if and only if f(x) = -f(-x) for all x in the domain of x.

else, f(x) is neither ODD nor EVEN..

## How do you determine if a function is even or odd Khan Academy?

If we get an expression that is equivalent to f(x), we have an even function; if we get an expression that is equivalent to -f(x), we have an odd function; and if neither happens, it is neither!

## What does an odd graph look like?

If the function is odd, the graph is symmetrical about the origin. … These graphs have 180-degree symmetry about the origin. If you turn the graph upside down, it looks the same. The example shown here, f(x) = x3, is an odd function because f(-x)=-f(x) for all x.

## Is there a function that is both even and odd?

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. … Also, the only function that is both even and odd is the constant function f(x)=0 f ( x ) = 0 .

## What does it mean when a function is odd even or neither?

DEFINITION. A function f is even if the graph of f is symmetric with respect to the y-axis. Algebraically, f is even if and only if f(-x) = f(x) for all x in the domain of f. A function f is odd if the graph of f is symmetric with respect to the origin.

## Is Tan An odd function?

Cosine and secant are even; sine, tangent, cosecant, and cotangent are odd. Even and odd properties can be used to evaluate trigonometric functions.

## Is 0 an even or odd function?

We could also think even and odd functions as the following to get f(x)=0 is a function that is both odd and even and go for some different functions: … Even functions have graphs that are symmetric with respect to y-axis. So, graph of f(x)=0 satisfies both conditions, therefore it is both odd and even.

## What does an even function look like?

The graph of an even function is symmetric with respect to the y−axis or along the vertical line x = 0 x = 0 x=0. Observe that the graph of the function is cut evenly at the y−axis and each half is an exact mirror of the another.

## What is the only number that is both odd and even?

Every integer is either even or odd, and no integer is both even and odd. This includes 0, which is even. Figure out whether 1729 is an odd or even number. Since the remainder obtained on dividing 1729 by 2 is 1, 1729 is an odd number.
