(a)
To sketch: The graph of the function by making the table containing its value.
(a)

Answer to Problem 15PPS
The graph of the function is curve and it’s shown in graph above in green curve.
Explanation of Solution
Given:
Concept used:
The graph of the function
The graph can be defined by the graph of
The graph of the function is special case of the graph of an equation.
Calculation:
Table of values and graph.
Using different value of
The graph of the function
Hence, the graph of the function is curve and it’s shown in graph above in green curve.
(b)
To find: The consecutive integer value of x between the zeroes is located.
(b)

Answer to Problem 15PPS
The zeroes of the function lied at
Explanation of Solution
Given:
Concept used:
The zeroes of the function resembled the function equates to zero.
The zero normally lies in between negative number and positive number.
Therefore, the consecutive number will negative approaches zero and positive approaches to zero except
Calculation:
Table of values and graph.
Using different value of
The points in the graph so collected will form a graph for the given equation.
The changes in sign from the result indicates that there are zeroes between
Since, the sign of the function changes from negative to positive.
Hence the zeroes of the function lied at
(c)
To find: The Abscissa of the relative
(c)

Answer to Problem 15PPS
The
Explanation of Solution
Given:
Concept used:
Relative maxima:
Which is greater point than the points directly beside it at both sides.
Whereas,
Relative minimum:
Any point which is lesser than the points directly beside it at both sides.
Calculation:
The relative maxima and minima can be calculated as:
The value of
The value of
Hence relative maximum lied near
