If f is a polynomial or a rational function, then lim, +a f (x) = f (a), providing that a is in the domain of /. In other words, we can do a direct substitution to find the limit. True FalseWhen we try to find lim, + f (@), if direct substitution gives we can try (Hint: There are more than 1 correct answer here.) rationalizing it factoring taking the square root taking the reciprocalIf 11m; _.|" {m} 31 , that means the limit DNE [dues not exist as a real number]. and the innite limit is me.
