a.
To find:the domain and range of given relation by observing the graph.
a.
Answer to Problem 12CFU
Domain =
Range =
Explanation of Solution
Given information:
Calculation:
Since, all the possible values of x and y in relation represents domain and range respectively. In Also, there is a continuous line in the graph that extends infinitely. Thus, the domain and range both are same, i.e.
b.
To state: yes/no whether the graph represents a function along with explanation.
b.
Answer to Problem 12CFU
Yes, because it passes the vertical line test.
Explanation of Solution
Given information:
Calculation:
The slope intercept of the above graph is as follows:
Yes, this relation is a function. Since for every possible value of x, there is only one corresponding value of y. So, it passes the vertical line test, hence this relation is a function.
