The Deep Dive
To analyze the function \( f(x) = \frac{x^{2}+10x+24}{x^{2}+8x+16} \), we first simplify it. The numerator factors to \( (x+4)(x+6) \), and the denominator factors to \( (x+4)(x+4) \) (or \( (x+4)^2 \)). This gives us \( f(x) = \frac{(x+4)(x+6)}{(x+4)^2} \) for \( x \neq -4 \). **Domain:** The only restriction comes from the denominator. Setting \( (x+4)^2=0 \) gives \( x = -4 \). Thus, the domain of \( f(x) \) is all real \( x \) except \( x = -4 \): A. The domain is all real \( x \), except \( x = -4 \). **X-intercepts:** To find the \( x \)-intercepts, set \( f(x) = 0 \) by setting the numerator to zero: \( (x + 4)(x + 6) = 0 \) gives \( x = -4 \) and \( x = -6 \). However, \( x = -4 \) cannot be an \( x \)-intercept because it is not in the domain. Therefore, the only \( x \)-intercept is: A. The \( x \)-intercept(s) is/are at \( x = -6 \). **Y-intercepts:** To find the \( y \)-intercept, substitute \( x = 0 \) into the function: \( f(0) = \frac{0^2 + 10(0) + 24}{0^2 + 8(0) + 16} = \frac{24}{16} = \frac{3}{2} \). Thus, the \( y \)-intercept is: A. The \( y \)-intercept(s) is/are at \( y = \frac{3}{2} \).
