(a)
To show: The equation that represent salary of a person is given by
(a)
Explanation of Solution
Given information: The initial salary of a person is $36,500 and a contract promises to increase salary each year for 4 years at 3.5% rate.
Proof:
The general formula for an amount is given by,
To find the first year salary
To find the second year salary
To find the third year salary
To find the fourth year salary
So, the above function corresponds to
Hence, it is proved that the Salary increment is given by
(b)
To find: The graph of the function that represents salary and the values of t for which the function is continuous.
(b)
Answer to Problem 52E
The graph of the function
Explanation of Solution
Given information: The initial salary of a person is $36,500 and a contract promises to increase salary each year for 4 years at 3.5% rate.
Calculation:
To draw the graph of the function
Press “ON” button to open the calculator. Press
Set the window at
Figure (1)
From the graph it can be seen that the function is not continuous at points
Therefore, the graph of the function
