Answer:
He didn't calculate the b-value correctly.
Step-by-step explanation:
The given parent function is:

The transformation is of the form:

The period is given by

If we want the new function to have a period of

Then we solve the following equation for b.



will translate the graph horizontally to the right by

units.
+d shifts the graph up by d units.
The new function then becomes:

Answer: -180
Step-by-step explanation:
I just had this question for homework too!
c = 4v + 1
v + c = 121
Now use substitution.
v + 4v + 1 = 121
5v + 1 = 121
5v = 120
v = 24
The answer is 24.
