Answer

The function \( f(x) = \frac{3x - 4}{(x + 2)^2} \) has a vertical asymptote at \( x = -2 \), a horizontal asymptote at \( y = 0 \), an x-intercept at \( \left( \frac{4}{3}, 0 \right) \), and a y-intercept at \( (0, -1) \).

Beyond the Answer

This function features a polynomial in the numerator and a quadratic polynomial in the denominator, making it a rational function. Interestingly, the denominator can be factored as \( (x + 2)^2 \), leading to insights about its behavior near critical points. The vertical asymptote occurs where the denominator equals zero, which means \( f(x) \) approaches infinity as \( x \) approaches -2. To truly grasp how \( f(x) \) behaves, consider plotting the function to visualize its asymptotes and intercepts. You’ll notice it has a horizontal asymptote at \( y = 0 \) as \( x \) approaches infinity, indicating that the function levels off at 0. Additionally, analyzing limits can help you understand the values closer to the asymptote and confirm if the function has any holes at points of discontinuity.
