The graph of a function f is the set of all points x f x.

Determine the domain of the function graphed above. 5 2 5 4 3 2 1 1 1 2 3 4 5 2 3 4 5 domain. Solution for find the domain and range of the function graphed below. Hence for a function f defined by its graph the implied domain of f is the set of all the real values x along the x axis for which there is a point on the given graph.

0 4 4 c range. Find domain and range from graphs another way to identify the domain and range of functions is by using graphs. Small sets of points are generally.

Let s say you re working with the following function. We use piecewise functions to describe situations in which a rule or relationship changes as the input value crosses certain boundaries for example we often encounter situations in business for which the. 3 2 1 5 4 3 2 3 1 4 5 2 3 5 6 a domain.

When functions are first introduced you will probably have some simplistic functions and relations to deal with usually being just sets of points. Previous question next question transcribed. The range is the set of possible output values which are shown on the y axis.

Now check the area below 2 by plugging in 3 for example to see if the numbers below 2 can be plugged into the. If you do not see an. This video provides two examples of how to determine the domain and range of a function given as a graph.

These won t be terribly useful or interesting functions and relations but your text wants you to get the idea of what the domain and range of a function are. Y 1 x 2 4. Find the domain and range of the rational function graphed below.
