What would the graphs of each question look like?

Just put the equation for each question in www.desmos.com/calculator, so I can see how you graph these.

 

Question 1:

 

 

Question 2:

 

Thanks to anyone who helps! smiley

First one

 

We have the form    y = Asin (Bx)

 

A = 20/2 = 10

B = 2pi / period  = 2pi / 8   =  pi/ 4

C = midline =  y = 0

 

The function is

 

y = 10sin [ (pi/4] x  )

 

Here is the graph :  https://www.desmos.com/calculator/5dmvrecajh

Second one

 

A =  6

The period is 20 sec

B = 2pi /period =  2pi /20 =  pi/10

C = the normal midline is y = 0

The midline here is y = 10.....so C = 10

 

The function is 

 

y = 6sin [ (pi/10) x ] + 10
