Explanation of Solution
Given information: Given equation is;
Calculation:
It helps a lot that b is restricted to a positive integer because otherwise it would be much more complicated. The period is found by first factoring:
So since b is a positive integer, then there is one complete cycle when b = 1, 2 complete cycle when b =2, 3 complete cycle when b = 3 etc.
The place shift is
The only thing a does is vertical stretch. So then;
