To find the vertical and horizontal asymptotes of the function \( f(x) = \frac{-5}{-4x + 2} \), let's start with the vertical asymptote. Vertical asymptotes occur where the denominator is zero and the function is undefined. Setting the denominator equal to zero: \[ -4x + 2 = 0 \] Solving for \( x \), we get: \[ -4x = -2 \quad \Rightarrow \quad x = \frac{1}{2} \] So, there is a vertical asymptote at \( x = \frac{1}{2} \). Now, for the horizontal asymptote, we look at the degrees of the numerator and the denominator. The function is a rational function where the degree of the numerator (which is a constant, so degree 0) is less than the degree of the denominator (which is linear, hence degree 1). According to rational function behavior, when the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is \( y = 0 \). In summary: - Vertical Asymptote: \( x = \frac{1}{2} \) - Horizontal Asymptote: \( y = 0 \) To graph them, you'll draw a dashed line for the vertical asymptote at \( x = \frac{1}{2} \) and a dashed line for the horizontal asymptote along the x-axis at \( y = 0 \).
