Concept explainers
To Give: The domain and range of the function whose complete graph is shown in red.
Answer to Problem 13OE
Domain {-2,-1,0,1,2,3,4} and Range {-2,0,2,4}.
Explanation of Solution
Given information:Complete graph of the function is shown in below figure.
Calculation:
The coordinates of the points of the graph are (-2,-2),(-1,-2),(0,0)(1,2),(2,2),(3,4),(4,4).
The domain includes x -values which the function is allowed to receive as inputs.
So, the domain of the function=All x -values of all the points of the function.
So , domain is {-2,-1,0,1,2,3,4}.
The range includes all y -values that the function yields given all inputs from its domain.
So , the range of the function is=All y -values of all the points of the function.
So, range is {-2,0,2,4}.
