Concept explainers
To sketch the graph of the given functions on same co-ordinate system

Explanation of Solution
Given:
The given functions are:
Calculation for graph:
Consider
Values of x | Values of f (x ) |
0 | 0 |
1 | 1 |
-1 | 1 |
2 | 2 |
-2 | 2 |
By taking different values of x , the graph can be plotted.

Graphs on the same co-ordinate system:
Verification:
Using graphing utility to draw the graph of given functions,
Interpretation:
From above graph, it is clear that, the drawn sketch and above graph are identical to each other.

Precalculus with Limits: A Graphing Approach
- A 20 foot ladder rests on level ground; its head (top) is against a vertical wall. The bottom of the ladder begins by being 12 feet from the wall but begins moving away at the rate of 0.1 feet per second. At what rate is the top of the ladder slipping down the wall? You may use a calculator.arrow_forwardExplain the focus and reasons for establishment of 12.4.1(root test) and 12.4.2(ratio test)arrow_forwarduse Integration by Parts to derive 12.6.1arrow_forward
