1. ## Word Problem

So I get to the end of my math worksheet, and come across this monster. I am totally lost on this. I don't even remember it from class.

"According to the data the relationship between the minimum voltage f(x) (in milivolts) needed to excite a nerve fiber and the time X (in milliseconds) during wich the current flows can be approximated by the function f(x)= 19.6216+23.2x/x+0.113

A) identify any vertical and horizontal asymptotes (equations) (4 decimal digits)
B) Identify any vertical and horizontal intercepts (4 decimal digits)

A) identify any vertical and horizontal asymptotes (equations) (4 decimal digits)
B) Identify any vertical and horizontal intercepts (4 decimal digits)
A) As x-> +/1 infty f(x) -> 23.2, this is the only horizontal asymtote,
y-> infty as x->-0.113, this is the only vertical asymtote.

B) These are the value of f(0), and the roots of f(x)=0
