Multiple Choice
Ariel claims that a pulse is described by the equation 
Where x and y are measured in cm and t in s.Miranda says that it is not possible to represent a pulse with this function because a wave must be a function of x + vt or x − vt.Which one,if either,is correct,and why?
A) Ariel,because x2 - 6.0xt + 9t2 = (x - 3.0t) 2.
B) Ariel,because a pulse is not an infinite wave.
C) Miranda,because (x - 3.0t) 2 is the same as (3.0t - x) 2.
D) Miranda,because a pulse is not an infinite wave.
E) Miranda,because
is infinite when x = 0.
