Diagram of simple filtration: oversize particles in the feed cannot pass through the lattice structure of the filter, while fluid and small particles pass through, becoming filtrate.
An odd function can be identified by replacing both the x and y values with -x and -y values. If the values in your equation are the opposite (positives are negatives and negatives are positives), then the function is odd. Take, for example, this equation y = x^2.
In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is the function that relates each real number x to its square x 2.The output of a function f corresponding to an input x is denoted by f (x) (read  f of x ). In this example, if the input is â3, then the output is 9, and we may write f (â3) = 9.n inverse function for f, denoted by f â1, is a function in the opposite direction, from Y to X, satisfying. That is, the two possible compositions of f and f â1 need to be the respective identity maps of X and Y.
