Concept explainers
To sketch: the graph of the function shown by given table and to find whether the function is linear or nonlinear.
Answer to Problem 7PPE
The function is nonlinear.
Explanation of Solution
Calculation:
Consider below table. It represents the length
Pencil Sharpening | ||||||
0 | 3 | 6 | 9 | 12 | 15 | |
7.5 | 7.5 | 7.5 | 7.5 | 7.4 | 7.3 |
Using the above table, make a graph. Here, dependent variable is length of pencil and independent variable is time for which pencil sharpened. Thus, write
Graph is as follows-
A nonlinear function is a function whose graph is not a line of part of a line.
Observe the graph. Found that, this is a curve not a line.
Thus, the function is nonlinear.
