At t = 0 , a transverse wave pulse in a wire is described by the friction .

y(x,t = 0) = 6/ (x^2+ 3)

Where x and y are in meters , The pulse is traveling in the positive x direction with a speed of 4.5 m/s . Which formula correctly describes the pulse at time t ?

1) y = 4.5t + 6 / x^2 + 3

2) y = 4.5t+ [ 6/ x^2 + 3]

3) y = 6 / [(x + 4.5 t)^2 + 3 ]

4) y = 6 / [(x - 4.5 t)^2 + 3 ]

5) y= -4.5t +6 / (x^2+3)

6)y=6-4.5t/x^2+3
