function in graphs. The domain is 1 0 2 3 4 and the range is 2 3 4 7. The graph of the function is the set of all points xy x y in the plane that satisfies the equation y f x y f x.
Graphing Functions In this section we discuss graphing functions including several examples of graphing piecewise functions. Modeling is the process of finding the relationships between quantities Sometimes we may not know an expression for a function but we do know some values maybe from an experiment. If you plot the graph then it look like the one below.
A graph of a function is a special case of a relation.
The graph of the function is the set of all points xy x y in the plane that satisfies the equation y f x y f x. Find any zeros first. The domain is 1 0 2 3 4 and the range is 2 3 4 7. In addition we introduce the concept of function composition.
