Is there a specific way you would like me to answer this? For example, problem format, essay, or just a sentence.
OpenStudy (anonymous):
it is multiple choice
OpenStudy (john_es):
Do you know the definition of period?

You should find two points in the graph that repeats in the y axis. Then measure the distance between those points in the x axis.
OpenStudy (john_es):
Something like this, but not strictly this.
OpenStudy (john_es):
For example, the point (1,5) and the point (5,5). Do you see them?
OpenStudy (anonymous):
yes
OpenStudy (john_es):
Do you see that the graph repeats again after that points?

yes
OpenStudy (john_es):
Then the period should be the x distance between those points: 5-1=4
OpenStudy (john_es):
For the amplitud, you should see what is the maximum y and minimum y that your function reaches.
In the graph, you see that the maximum y is 5, and the minimum -2. Then the amplitud is the half way between them, (5-(-2))/2=7/2=3.5
And then you have option 3.
