Concept explainers
a.
An example of scattered plot that can be represented by quartic type of function.
a.
Explanation of Solution
When a
Here in the diagram we can see that the scatter plot changes direction three times. So a quartic function would best fit the scatter plot.
b.
An example of scattered plot that can be represented by quadratic type of function.
b.
Explanation of Solution
When a scatter plot changes direction one time then it is considered as quadratic function.
Here in the diagram we can see that the scatter plot changes direction one time. So a quadratic function would best fit the scatter plot.
c.
An example of scattered plot that can be represented by cubic type of function.
c.
Explanation of Solution
When a scatter plot changes direction two times then it is considered as cubic function.
Here in the diagram we can see that the scatter plot changes direction two times. So a cubic function would best fit the scatter plot.
