What is the period of the graph y=1/2sin (pix)+3?
A- 3
B- 1/2
C-pi
D-2
1 answer:
The period is 2.
Normally the period of sin(x) is 2pi, but the pi inside the sin(pix) is a horizontal compression by a factor of 1/pi. So 2pi·1/pi = 2
The "1/2" and "+3" do not impact the period. Those just impact the amplitude (vertical aspect) of the graph.
