Question

Evaluate the function y = x+5/x^2+7x+12 at x=-5 x=1. Write undefined if appropriate.

Answer 1

\[y = \frac{x+5}{x^2 + 7x + 12} \]
@ x= -5,
\[y = \frac{(-5)+5}{(-5)^2 + 7(-5) + 12} \]

----------------------------------------
@ x = 1
\[y = \frac{(1)+5}{(1)^2 + 7(1) + 12} \]

Answer 2

undefined at -5... and @1 it is 3/10
