Asymptotes: Practice Questions

A function is given by \(f(x) = \frac{2x - 5}{x + 3}\). What are the equations of the vertical and horizontal asymptotes for the graph of this function?

Consider the function \(f(x) = \frac{2x + 1}{x - 5}\). Identify the equations of the vertical asymptote and the horizontal asymptote for the graph of \(y = f(x)\).

For the trigonometric function \(g(x) = \tan(2x)\), which of the following is an equation of an asymptote in the interval \(0^\circ \le x \le 180^\circ\)?

Identify the equation of the vertical asymptote for the function \(f(x) = \frac{3}{2x - 5} + 4\).

A function is defined as \(h(x) = \frac{ax + 5}{x - b}\). The graph of \(y = h(x)\) has a vertical asymptote at \(x = -4\) and a horizontal asymptote at \(y = 3\). Calculate the value of \(a + b\).

State the equation of the horizontal asymptote for the graph of the function \(f(x) = \frac{1}{x} + 7\).

Consider the function \( f(x) = \frac{3x^2 - 12}{x^2 - x - 6} \). By simplifying the expression, identify the equation of the vertical asymptote of the graph of \( y = f(x) \).

Consider the function \(g(x) = \frac{1}{x+2}\).
