If x is the wind speed in miles per hour and is greater than or equal to 5, then the wind chill
(in degrees Fahrenheit) for an air temperature of 00F can be approximated by the function f (x) = 289.173 - 58.5731x / x+1 , x ≥ 5
(a) Ignoring the restriction x ≥ 5, does f (x) have a vertical asymptote? If so, what is it?
(b) Does f (x) have a vertical asymptote within its domain?
(c) Does f (x) have a horizontal asymptote? If so, what is it?
