Concept explainers
To Give: The domain and range of the function whose complete graph is shown in red.
Answer to Problem 14OE
Domain {-3-2,-1,0,1,2,3} and Range {-1,1,3}.
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 (-3,1),(-2,1),(-1,3)(0,-1),(1,3),(2,1),(3,1).
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 {-3-2,-1,0,1,2,3}
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 {-1,1,3}.
