ANSWER:
Period: Take a look at how much time the data takes to make a complete cycle.
Amplitude: Find the average of all the data and find the values that are further away from this mean. This two data will be A and -A, where A is the amplitude.
Asymptote: Find a value the data approaches to, but never reaches.
Step-by-step explanation:
Remember that the period is the span of time between two identical datum. This way, we have to take a look at how much time the data takes to make a complete cycle.
Now, the amplitude is the maximum or minimum value the data takes. To get it we find the average of all the data and find the values that are further away from this mean. This two data will be A and -A, where A is the amplitude.
To find the asymptote, we have to take a look at a value the data approaches to, but never reaches.
