i have no idea where to start

g defined by

g(x) = x+4 / (2x+9)ln(x^2-15)

Find the equations of all vertical asymptotes (if any), of the function

I am brand new to maple and im having a very hard time. My teacher gave us an assignment but he didnt teach us how to use maple.

Can someone please explain to me how i can find the horizontal asym. of sqrt(9*x2 - 4*x + 2)+ 3*x - 5?

and how would i find the x and y intercepts?

thanks a lot
