To sketch: the graph of the given function rule and to explain of intervals on the axes of the graph. To find whether the graph is continuous or discrete.
Answer to Problem 22PPE
This relationship should be represented by discrete graph.
Explanation of Solution
Given information:
The total weight
Calculation:
Consider total weight a tractor trailer is represented by
Since
Make table of values using this function rule. Choose any
0 | 2 | 4 | 6 | 8 | |
37000 | 45400 | 53800 | 62200 | 70600 |
Graph each ordered pair
Since there are maximum8 cars can place on tractor trailer. This is represented by inequality
Observe the graph. Found that each car has specific weight. So cannot place connect all points by the definition, discrete graph is composed of distinct, isolated points.
Thus, this relationship should be represented by discrete graph.
