Question 211263: Can you pls help me
3.)y=x^2-4x
•Graph this original function in its entire domain but coloring green that portion of the graph over the limited domain x>=2,
•Find its inverse over x>=-4,
•On another set of coordinate axes, graph this inverse. Color it blue. On this same set of coordinate axis, graph the original f(x) on the limited domainx>= 2, y>=-4 & color it green.
•Draw the line y = x in dotted form.
•Label each graph including the dotted line by the corresponding equation and domain and range. Use the textbox for these labels.
Thanks alot for everybody who is willing to help.I dont know how to post a comment that's why I include this to my query

Question 217944: Find the inverse of y = (3x) / (x-2) and state the domain of the inverse.
I have tried switching the x's for y. I get stuck at this step of the problem:
{(xy)-(2x)} / 3
I've looked online for inverse help, but nothing makes sense! Everyone just says switch the x for y.
Thanks
