So find f(3.999), f(4.001), f(-3.999), and f(-4.001).
]]>ok if i factor the denominator.. i find the vertical asymptotes to be x = 4, x = -4.
The 2nd part of the problem asks:
Describe the behavior of f(x) to the left and right of each vertical asymptote.. I'm not sure what i need to write for this.
