Which function is shown on the graph?
What is the frequency of the sinusoidal graph?
Which equation represents the function on the graph?
The graph is (1/2) as high s the normal sine graph and is also reflected about the x axis
So.....the correct equation is f(x) = (-1/2)sin x
The period is pi
The frequency = 1 /period = 1 / pi
This is the sine graph with a period compressed by a factor of 2
f(x) = sin (2x)
