To find the vertical asymptote (V.A) of the function \( F(x) \), we need to identify where the denominator is equal to zero without being canceled out by the numerator. The denominator is \( (x-4)(x+2) \). Setting \( x-4 = 0 \) gives us \( x = 4 \) as a vertical asymptote. Since \( x = -2 \) is canceled out, we don't count it as a V.A. The horizontal asymptote (H.A) can be determined by analyzing the degrees of the polynomials in the numerator and the denominator. Both the numerator and the denominator are quadratic (degree 2). Therefore, the horizontal asymptote is found by taking the ratio of the leading coefficients, which are both 1. Thus, the horizontal asymptote is \( y = 1 \). The hole in the function is at \( x = -2 \) due to the cancellation of the term \( (x+2) \), which indicates a point of discontinuity that doesn't affect the overall behavior of the function elsewhere. To find the x-intercept, we set the numerator equal to zero. The numerator \( (x+2)(x+4) = 0 \) gives us two x-intercepts at \( x = -2 \) and \( x = -4 \). However, since \( x = -2 \) is a hole, the only valid x-intercept is \( x = -4 \). In summary: V.A \( = 4 \) H.A \( = 1 \) Hole \( = x = -2 \) x-intercept \( = -4 \)
