Find Horizontal and Vertical Asymptotes
Vertical asymptotes are generated by the ZEROS of the denominator.
Horizontal asymptoes describe the behavior of the graph as the input values get larger or smaller.
Vertical asymptote:

To graph the equation y = (2x + 1)/(x  5), you can follow these steps:

Determine any vertical asymptotes by setting the denominator equal to zero and solving for x. In this case, x  5 = 0, so x = 5 is a vertical asymptote.

Determine any horizontal asymptotes by comparing the degrees of the numerator and denominator. Since the degree of the numerator (1) is less than the degree of the denominator (1), there is a horizontal asymptote at y = 0.

Find the xintercept by setting y = 0 and solving for x. In this case, (2x + 1)/(x  5) = 0, which gives 2x + 1 = 0. Solving for x, we get x = 1/2.

Plot the vertical asymptote at x = 5 and the horizontal asymptote at y = 0.

Choose some xvalues to the left and right of the vertical asymptote (e.g., x = 4 and x = 6) and calculate the corresponding yvalues using the equation. Plot these points on the graph.

Connect the plotted points with a smooth curve, approaching the vertical asymptote and horizontal asymptote as x approaches infinity or negative infinity.
The resulting graph should show a vertical asymptote at x = 5, a horizontal asymptote at y = 0, and a curve passing through the xintercept at x = 1/2.

When evaluating a onesided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
