Graph the rational function: f(x) = (2x + 1) / (x - 4)

• To graph rational functions, only the numerator needs to be considered.

• Graphing rational functions involves finding the derivative of the function.

• The graph of a rational function always intersects the x-axis at the point where the denominator is zero.

• Graphing rational functions involves finding vertical and horizontal asymptotes, plotting these asymptotes, and analyzing the behavior of the function to sketch the graph.
