Displacement of Transverse Waves HELP!!

1. The problem statement, all variables and given/known data
At time t=0, the displacement of a transverse wave pulse is described by y=2/(x^(4) +1), with both x and y in cm. Write an expression for the wavefunction as a function of position x and time t if it is propagating in the positive x direction at 3.0 cm/s

2. Relevant equations
I'm not quite sure if this has to do with partial derivatives...and if it does, I don't really understand partial derivatives...

3. The attempt at a solution
I know that v= 3.0 cm/s...

Re: Displacement of Transverse Waves HELP!!

With a velocity of propagation v = 3.0 cm/s, the wave is shifting along the x-axis. The concept here is mathematical: what would you do to this equation to make the function shift left or right? There is no need for partial derivatives.
