To graph this function, we can apply a translation 2 units up.
When doing this, we will obtain that the midline will be located at y=2 and that the minimum and maximum values will be 1 and 3 respectively.
We know this by adding 2 to the original values of sine function.
The midline of a normal sine function is y=0. If we add 2, it is y=2.
The minimum value of the sine function is -1. If we add 2, it is 1.
The maximum value of the sine function is 1. If we add 2, it is 3.
According to the instructions, you have to plot one point on the midline, and one of the minimum and one of the maximum values.
We know that the minimum value of sine is located at 3π/2 and that the maximum is located at π/2, so these points have to have those x coordinates respectively.
Plot the following points:
Those are (1.57, 3), (3.14, 2) and (4.71, 1).
The graph should look like this:
