Hello! Please please please help! I am stuck at graph transformation questions... Thank you!

2)

The equation of a graph is y = (ax)/(bx-1), and y= c is the horizontal asymptote while x = d is the vertical asymtote of this graph. Given that c = d = 1/2, what are the values of a and b?

3) Given the graph of y = (ax)/(bx-1), what transformations do I need to perform on the graph to obtain the graph of y = |(ax)/(bx+1)|?

4) The curve of y = x^2 + (3/x) undergoes a reflection about the line y=4 and the point (2, 5.5) is mapped onto (2, 2.5). Hence find the equation of the new curve in the form y = f(x).

Thank you!
