Does a travelling wave in one dimension represented by a function of a linear combination of x and t,i.e., `y=f(ax+-bt)` represented a travelling wave?

Explanation

To determine whether the function \( y = f(ax \pm bt) \) represents a traveling wave, we can follow these steps:

### Step 1: Understand the Wave Equation
A traveling wave in one dimension can generally be represented by the equation:
\[ y = f(\omega t \pm kx) \]
where \( \omega \) is the angular frequency and \( k \) is the wave number.
