Question

math

Answer 1

Is there a specific way you would like me to answer this? For example, problem format, essay, or just a sentence.

Answer 2

it is multiple choice

Answer 3

Do you know the definition of period?

Answer 4

no.

Answer 5

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.

Answer 6

Something like this, but not strictly this.

Answer 7

For example, the point (1,5) and the point (5,5). Do you see them?

Answer 8

yes

Answer 9

Do you see that the graph repeats again after that points?

Answer 10

yes

Answer 11

Then the period should be the x distance between those points: 5-1=4

Answer 12

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.
