How would you write the asymptote equation for y=2/x?
Also, how can you describe the single transformation from y=1/x to y=4/x

Think of the first as y=2(1/x) so for every x value, the y value is twice as much, therefore the asymptopes dont change y=0 x=0
For the second, its a vertical stretch scale factor 4, as all y values increase by 4 times.

If you want to work out the asypototes: to get the vertical asymptotes solve the denominator for 0 e.g. x=0. To get the horizontal asmyptotes you want to divide, which clearly shows that y=0.
