Y= 3 cos(x)+2 I need help solving this

Use the form acos(bx−c)+dacos(bx-c)+d to find the variables used to find the amplitude, period, phase shift, and vertical shift.

a=3a=3

b=12b=12

c=0c=0

d=0d=0

The trig function can be graphed using the amplitude, period, phase shift, vertical shift, and the points.

Amplitude: 33

Period: 4π4π

Phase Shift: 00 (00 to the right)

Vertical Shift: 00

xf(x)03π02π−33π04π3xf(x)03π02π-33π04π3

3.

Step-by-step explanation:

The others are correctly graphed residual plots, and residual plots shouldn't make any specific pattern. Number three represents a V or U shape.
