(a)
To find: The type of function that is represented by the data.
(a)
Answer to Problem 18E
The required graph shows a cubic polynomial function.
Explanation of Solution
Given information:
The graph representing the function is:
Consider the given graph of values as:
Focus on the graph that is formed with the points:
It is seen that a cubic polynomial is represented by the graph.
Hence, the required graph shows a cubic polynomial function.
(b)
To find: The degree of the polynomial from the graph.
(b)
Answer to Problem 18E
The required graph shows a third degree constant feature.
Explanation of Solution
Given information:
The graph representing the function is:
Consider the given graph of values as:
It is seen that a cubic polynomial is represented by the graph.
So, the third order finite difference of the function should be constant as the graph represent a third degree polynomial function.
Hence, the required graph shows a third degree constant feature.
