Use the rational function to find the indicated function values. If a function value does not exist, state so. \( f(x)=\frac{x^{2}-4 x-32}{x-4} ; f(2), f(4), f(8) \)

What is a proportional relationship?

138. Hallar el resto de la división \( \frac{[(x+4)(x+3)(x+2)(x+1)+3]^{4}}{x^{2}+5 x+5} \) \( \begin{array}{lllll}\text { a. } 25 & \text { b. } 34 & \text { c. } 43 & \text { d. } 27 & \text { e. } 6\end{array} \)

Determine the value of \( C \) that makes each expression a Perfect square. \( x^{2}+14+c \)

9.- Desarrollar: \( (13 x-17 y)(17 y+13 x)= \)

Expand. Your answer should be a polynomial in standard form. \( (-f+10)(3 f-1)=\square \)
