I don't 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 x4
4. y= sin(x4)
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/functiongraphs/
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. 
thank you!

how does that tell how the graph of the function is related to a basic trigonometric graph?
