Question

PLEASE HELP!!!!!!!!!!!!!!!!!!!!!

Answer 1

Answer:

  plot the points (0, 2) and (π, 4)

Step-by-step explanation:

To use your sine plotting tool, you need two points on the graph. The midline point is given for you. It is the y-intercept, (0, 2).

The maximum amplitude point is 1/4 of a period from this midline point. The frequency is 1/(4π), and the period is the inverse of frequency:

  T = 1/f = 4π

So, 1/4 of a period is ...

  T/4 = (4π)/4 = π

The peak value of the function is the amplitude added to the midline, so is 2+2 = 4.

The second point you need to plot is the peak value, (π, 4).

Your points are (0, 2) and (π, 4).
