finding the x-intercept when the function has an asymptote on a TI-84?

Hey all,

So, I have come across a problem that requires me to input a function into my TI-84 and provide the x-intercept.

The function has an asymptote at X=0, but only the segment from (-infinity, 0) has an x-intercept. I have been trying to figure out the x-intercept value by doing the traditional method of trace-->intercept, but this doesn't seem to work. I first select the part of the curve underneath the x-axis as my "first curve", but then when I try and select the part above the x-axis, the calculator doesn't seem to process that as my "second curve". As a result, I can't find out the x-intercept!

Can anybody help me out with this?

How can we help you if you do not provide us the formula of the function?
