Concept explainers
To calculate: the domain and range of the function.
Answer to Problem 27PT
Domain:
Range:
Explanation of Solution
Given information: Given a graph of the function.
Formula used:
Domain is the set of all real x values where function is defined.
Range is the set of all yvalues(output).
Calculation:
In the given graph,
Vertex of the graph is (-3,-2)
We see that, graph covers negative and positive all real x.
So, domain is all real x.
To find the range, lowest y value is -2 and graph goes to infinite.
So, the range is
