(a)
To Find: The maximum value.
(a)

Answer to Problem 73E
Maximum volume is
Explanation of Solution
Given: An open box of maximum value is to be made from a square piece of material,
The table shows the volume of the box for various heights
The maximum value from the table is
(b)
To Plot: The plot the points from the table. Does the relation defined by the ordered pairs represent
(b)

Answer to Problem 73E
Yes the relation is a function.
Explanation of Solution
Given: An open box of maximum value is to be made from a square piece of material,
The table shows the volume of the box for various heights
The graph by plotting the points is shown below
The relation is a function because for every height there is only one volume.
(c)
To Find: If
(c)

Answer to Problem 73E
Explanation of Solution
Given: An open box of maximum value is to be made from a square piece of material,
Thus the function is
And
Domain:
(c)
