Question

Graph y = -3 sin (pi/2 x) +2 in the interactive widget.

Answer 1

We have to find some values to plot the graph. Doing so, we have:

x y

0 -3*sin(0)+2=-3*0 +2 = 2

1 -3*sin(π/2)+2 = -3*(1) +2 = -1

2 -3*sin(2*π/2)+2 = -3*(0) +2 = 2

3 -3*sin(3*π/2)+2 = -3*(-1) +2 = 5

4 -3*sin(4*π/2)+2 = -3*(0) +2 = 2

Plotting the points and drawing the graph we have:
