Which is not a correct description of the graph below?

Question

The graph shows a sine wave with a minimum value of negative 1 and a maximum value of 1. The wave completes 1 cycle in an interval from 0 to 2 pi. The wave passes through (0, 0), slopes down and hits a minimum value of negative 1 at pi over 2, has a value of 0 again at pi, hits a maximum value of 1 at 3 pi over 2 and has a value of 0 again at 2 pi.

A) y= sin (0+n)
B) the graph of y = cos 0 shifted to the left by pi/n units
C) the graph of y = sin 0 shifted to the left by pi/2 units
D) y = sin 0 shifted to the left by pi units

Answer 1

A) y= sin (0+n)
