The data from the previous table is plotted to the right. The distance the boat traveled is on the x-axis, and the vertical position of the barnacle is on the y-axis. The graph follows the pattern. This is the pattern for a function. The amplitude is 1 . The vertical shift is . An equation for this graph is y = .

An equation for this graph is y = sin (x)

Step-by-step explanation:

A= 1

V.S= 0

y=sin(x)

1) the graph follows the  zero-max- zero -min- zero (2nd option)

2) sine (1st option)

3) Amplitude is 1    vertical shift is 0     equation for this graph is y = sinx
