To get a better look at the graph, you can click on it. The curve above is the graph of a sinusoidal function. It goes through the point (4,0). Find a sinusoidal function that matches the given graph. If needed, you can enter pi =3.1416... as \'pi\' in your answer, otherwise use at least 3 decimal digits. f(x) = You have attempted this problem 6 times. Your overall recorded score is 0%.

Solution

amplitude A=4

period = 2pi/B =4

B=pi/2

phase shift =-C/B =2

-C/(pi/2)=2

C=-pi

general sineusidal function is y =Acos(Bx +C)

y =4sin((pi/2)x -pi)

or

y =-4sin((pi/2)x)
