a.
To write the domain and range for the relation
a.
Answer to Problem 1.6.2P
Domain is (2, 3, 5, 5, 6, 8, 8, 9)
Range is (2, 6, 8, 10, 16, 12, 18, 14)
Explanation of Solution
Given information:
A graph
Calculation:
From the given graph,
The points observed are: {(2, 1)(3, 6)(5, 8)(5, 10)(6, 16)(8, 12)(8, 18)(9, 14)}
Domain is the set of all values of x, hence domain is (2, 3, 5, 5, 6, 8, 8, 9)
Range is the set of all values of y, hence range is (2, 6, 8, 10, 16, 12, 18, 14)
b.
To tell how many customer spent over $12
b.
Answer to Problem 1.6.2P
3 people
Explanation of Solution
Given information:
A graph
From the graph given, value of range over 12 is 16, 18, 14. Hence, 3 people spent more than 12 dollar.
c.
To verify the statement
c.
Answer to Problem 1.6.2P
Yes, the statement is correct
Explanation of Solution
Given information:
A graph
It is observed that value of range is (2, 3, 5, 5, 6, 8, 8, 9)
Total products are 2+3+5+5+6+8+8+9=36
Value of range after adding=36
Hence, the statement is true.
