Question

i need help window pain graphing of trig functions
f(x)=-2sin(2(x-1))
f(x)=cos(1/2(x+1))
f(x)=3sin(x-pie/3)+1
f(x)=1/2sin(2x-4)+3
f(x)=2cos(3(x-1))-4 if you could do any of these it'd be great
one cycle...

Answer 1

there are a lot of ways you can graph these online here is the first with desmos.com

but i would urge you to look what exactly is going on with the graph

it si being compressed by 2, the amplitude is twice as high and shifted to left 1


why??

Answer 2

Amplitude is twice as high with -2 sinx, also - 2 inverts the graph
the period of we can think of the graph being compressed or streched is affected by:
sin2x

and lastly phase shift x-1 shifts it to the right X+1 to the left

using this as an example you can do the rest no prob bob
