MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Graph the function y = sin(x) for one full cycle.

Graph of y = sin(x) from x = 0 to x = 2π shows a straight line from (0,0) to (2π,0).

Graph of y = sin(x) from x = 0 to x = 2π shows a wave starting at (0,0), peaking at (π/2,1), returning to (π,0), dipping to (3π/2,-1), and returning to (2π,0).

Graph of y = sin(x) from x = 0 to x = π shows a wave peaking at (π/2,0.5) and returning to (π,0).

Graph of y = sin(x) from x = 0 to x = 4π shows multiple cycles with peaks at (3π/2,1) and (5π/2,1).

Graph the function y = cos(x) for one full cycle.

The graph of y = cos(x) for one full cycle is a wave starting at (0,1), going down to (π/2,0), reaching (-1,π), going up to (3π/2,0), and returning to (2π,1).

The graph of y = cos(x) has peaks at (π/4,1) and (5π/4,1).

The graph of y = cos(x) starts at (0,0) and ends at (2π,0).

The graph of y = cos(x) is a straight line from (0,1) to (2π,1).
