Answer:
The period of function is 5 and amplitude is 3.
Step-by-step explanation:
The period of the function is the time interval after which it repeats itself.
It means the time interval after which the same value of graph is attained.
In the above case looking at the peak point at time 5 seconds, the same value is obtained at time 10 seconds.
Thus the time interval is (10 - 5) 5 seconds.
Amplitude is the maximum value attained by the graph in the complete interval.
In the above case, the maximum value attained is 3.
