Concept explainers
a.
To find and interpret the zeros of the function and then sketch the graph using zeros.
a.
Answer to Problem 60E
The zeros are
Explanation of Solution
Given:
Calculation:
To find the zeros, put
Thus,
The zeros of the function is the time when the weight hits the ground (when height
Since, time cannot be negative,
Now sketch the graph using the zeros of the function
For
Thus, the vertex of the graph lies at
b.
To explain what does domain and range of the function represents.
b.
Answer to Problem 60E
The domain is the time (in seconds) when the weight is falling. The range is the height as the weight falls to the ground.
Explanation of Solution
The domain is the time (in seconds) when the weight is falling. The range is the height as the weight falls to the ground.
