Concept explainers
To graph: The polynomial function
Explanation of Solution
Given data:
The given polynomial function
Concept used:
Leading coefficient test: If the polynomial function
Zeros of thepolynomial are the points
Graph:
The given polynomial is
(i) Since the leading coefficient of given function is positive, therefore, graph of the function falls to the left and rises to the right.
(ii) Since,function
(iii) Some solutions of the function (computed by taking arbitrary values of x ) are:
x | -0.5 | 1 | 1.5 | 2 | 3.5 |
- 0.875 | -2 | -3.375 | -10 | 6.125 |
(iv) The continuous curve joining the calculated points (zeros and solutions), the graph of the polynomial function
Interpretation of the Graph:
The function
