find the y-axis intercepts for the function f(x)=1/x

(a) (0, 0)
(b) does not exist
(c) (1, 1)
(d) (0, 1)

For a short time after a wave is created by wind , the height of the wave can be modeled using y= a sin 2pi(t) / t where a is the amplitude and t is the period of the wave in seconds. how many times over the first 5 seconds does the graph predict the wave to be 2 feet high?
