Chapter 7 - Functions and Graphs - 7.2 Domain and Range - 7.2 Exercise Set: 13

Answer

Domain= {-4,-1,0,2,4} Range= (-2,-1,0,1,2}

Work Step by Step

For problem 13 a graph is given to us. The following points are on the graph. $(-4,-2) (-1,-1) (0,0) (2,1) (4,2)$ The domain is all your x values in an ordered pair. The range is all your y values in an ordered pair. Since these are points and not a continuous line, we must use set builder notation to list the domain and range. $Domain= {-4,-1,0,2,4}$ $Range = {-2,-1,0,1,2}$
