I dont understand this. can you please tell how you got each answer?

describe how the graph of each function is related to a basic trigonometric graph.

1. y= 1/2cos x

2. y= 2cos x+1

3. y= sin x-4

4. y= sin(x-4)

5. y= sin(3x)

6. y= cos(1/2x)

7. y= -cos x

8. y= -cos x+2

9. y= -4sinx

10. y= 4sin(-x)

Pleeease help! thank you!

In google type:

functions graphs online

When you see list of results click on: rechneronline.de/function-graphs/

When page be open in blue rectangle type:

1/2cos(x)

And click option: Draw

then type :

2cos(x)+1 OR 2cos (x+1)

And click option: Draw

etc.

You must write correct expresions.
