Consider the following functon,
(a) `y=x^(2)+2 alpha, tx`
(b) `y=(x+vt)^(2)`
Which among the above function can be characterized as a wave ?

Explanation

Given
Formula
For the function to be a wave function `((dy//dx))/((dy//dt))` should be a constant.
For function (a) :
`y=x^(2)+2alpha tx`
`(dy)/(dx)=2x+2alpha t " "....(1)`
`(dy)/(dt)=00+2alpha " "....(2)`
`((1)/(2)) rArr (dy//dx)/(dy//dt)=(2x+2alpha t)/(2alphax)`
(a)does not describe wave.
(b) satisfies wave fuinction.
