To Graph: The function
Answer to Problem 23WE
Domain {-2,-1,0,2} and Range {-1,0,1}.
Explanation of Solution
Given information:Given function is
Calculation:
The coordinates ofthe points of the graph are (-2,-1),(-1,0),(0,1),(2,-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 {-2,-1,0,2}.
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 {-1,0,1}.
Sketch the graph of the function by using the coordinates of the points of the graph.
Domain {-2,-1,0,2} and Range {-1,0,1 }.
