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.
Thanks to anyone who helps!
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
