To determine the equation of the axis of symmetry of with , we need to find the x-coordinate of the axis of symmetry. The axis of symmetry of a function is the vertical line that passes through the vertex of the parabola. For the function , the axis of symmetry is the vertical line passing through the point where the function is symmetric. Since the function is a rational function, the axis of symmetry is the vertical line passing through the x-coordinate of the vertical asymptote, which is .
Therefore, the equation of the axis of symmetry of with is .

The function has two types of asymptotes. First, the vertical asymptote occurs where the denominator equals zero; in this case, , giving us the vertical asymptote at . The horizontal asymptote can be found by observing the end behavior of the function as approaches infinity. As , approaches 2, so the horizontal asymptote is .
To elucidate this information on a graph, you’d plot the function by noting its key features. The vertical asymptote at appears as an indefinite line where the function does not exist. The horizontal asymptote at flattens out the graph as it approaches it. Intercepts can be found by setting to zero to find the x-intercepts and substituting for the y-intercept. After graphing, ensure all asymptotes and intercepts are labeled distinctly.
For the axis of symmetry, consider that the function is in the form of a rational function. In this case, the axis of symmetry aligns with the reflection over the vertical line between the points approaching the asymptote. Since doesn’t possess symmetry in the traditional sense, the axis that reflects any noticeable symmetry of the curve in relation to its undefined points would likely be found at —but note that this requires some interpretation, as typical axes might not be as straightforward for such functions.
