(a)
Answer to Problem 53E
The formula that gives the charge for
Explanation of Solution
Given information: The charge of a value park is
Calculation:
The charges are taken for the fraction of an hour. So, for the time period of
The charges for
So, the function is constant and equal to
Therefore, the formula that gives the charge for
(b)
To find: The graph of the function in part (a) and the points of discontinuity of function.
(b)
Answer to Problem 53E
The graph of the function is shown in Figure (1) and the points of discontinuity of function are
Explanation of Solution
Given information: The charge of a value park is
Calculation:
To graph a function
First press “ON” button on graphical calculator, press
Now, press the
The display will show the equations,
Now, press the
Figure (1)
As observed from the graph, the function is constant and continuous for all the values of
Also it is observed from the graph that the function is step function for values of
So, all the integer points between
Therefore, the points of discontinuity of function are
