A rational function is a quotient
of 2 polynomials such as:
f ( x)
1
x 1
The line x = 1 is a vertical asymptote
The line y = 0 is a horizontal asymptote

Review: Use the 1st derivative to determine:
1) where a function is increasing/decreasing.
2) critical numbers by setting derivative = 0 or where f(x) is undefined
3) the relative extrema using the 1st derivative
