Domain Piecewise Function

It has two pieces.

Domain piecewise function. In this graph the changing behaviour of a single function takes shape of different pieces or segments on graph while each segment is explained with the help of a sub function present in the original function. Piecewise is actually a way of expressing the function rather than a characteristic of the function itself but with additional qualification it can describe the nature of the function.

Let s look at the graph of this function. It has an infinite number of pieces. The absolute value function is a famous piecewise function.

The domain of any function is all the values that x can be for that function. 1 for x 0. Our domain is all real numbers due to our x values being continuous across the x axis since we have one shaded circle at x 0 on the linear function and one shaded circle at x 3 on the linear function and the constant function continues on infinitely to the right so even though the functions visually stop the graph is.

The domain of a function is the set of all inputs for which the function is defined. The floor function is a very special piecewise function. 0 0 x 0.

In mathematics a piecewise defined function also called a piecewise function a hybrid function or definition by cases is a function defined by multiple sub functions where each sub function applies to a different interval in the domain. Now the original question is what is the domain of the function. A piecewise function is made up of two or more functions each defined on a specific domain.

The graph of the following piecewise function is given as. F x x the floor function. 2x for x 0.
