how do you find the range of this function X2/X+2 without using the graph?
pls help

math 
Steve,
There is a vertical asymptote at x = 2, and y ranges from ∞ to +∞ near it
There is a horizontal asymptote at y=1, yet y cannot be equal to 1, since that would mean that (x+2) = (x2), or 2 = 2.
So, the range is all real numbers except y=1.
