a.
To describe: the graph of function related to the parent function
a.
Answer to Problem 21E
Graph is compressed horizontally by a factor of 0.2.
Explanation of Solution
Given information:
Calculation:
Since the function is multiplied by 0.2, so the graph is compressed horizontally by a factor of 0.2.
b.
To describe: the graph of function related to the parent function
b.
Answer to Problem 21E
The graph is stretched vertically by a factor of 7 and it is shifted downwards by 0.4 units.
Explanation of Solution
Given information:
Calculation:
Since x is multiplied by 7, which means that the graph is stretched vertically by a factor of 7 and then 0.4 is subtracted from the function, so it is then shifted downwards by 0.4 units.
c.
To describe: the graph of function related to the parent function
c.
Answer to Problem 21E
The graph is shifted to the left by one unit, it is stretched vertically by a factor of 9 and then it is mirrored along the x-axis.
Explanation of Solution
Given information:
Calculation:
First x is replaced with
