The period of sin is 2π.

The 3 is applied to the result of sin(x) which affects the y value.

All of the points will be shifted down 3 units.

Rely on your knowledge of the unit circle to figure out the values of sin on the x and y axis.

f(0)=3+sin(0)=3+0=3(0,3)

f(π2)=3+sin(π2)=3+1=2(π2,2)

f(π)=3+sin(π)=3+0=3(π,3)

f(3π2)=3+sin(3π2)=31=4(3π2,4)

f(2π)=3+sin(2π)=3+0=3(2π,3)
