You can put this solution on YOUR website! graph 2 cos (1/16x+1) Also find Amp,Per.Phase Shift.
**
Form of equation for cos function: y=Acos(Bx-C), A=amplitude, Period=2π/B, Phase shift=C/B
For given cos function:
2 cos (1/16x+1)
Amplitude=2
B=1/16
C=1
Period=2π/(1/16)=32π
1/4 Period=8π
Phase shift=C/B=1/(1/16)=16 (radians)(shift to left)
..
I don't have the means to graph given function but I will provide you with (x,y) coordinate with which you can draw the graph yourself for one period:
(-16,2), (9.1,0), (34.3, -2), (59.4,0), (84.5,2)
..
y-intercept (another point on the graph)
set x=0
y=2cos(1)
y=1.08
