lim as x approaches 3 of the function (3x^2-8)/(x-2)

We are tasked with finding the limit:

\[
\lim_{{x \to 3}} \frac{3x^2 - 8}{x - 2}
\]

### Step 1: Substitution to check if the limit can be evaluated directly.
First, substitute \( x = 3 \) into the function:

\[
\frac{3(3)^2 - 8}{3 - 2} = \frac{3(9) - 8}{1} = \frac{27 - 8}{1} = \frac{19}{1} = 19
\]

Since direct substitution does not result in any undefined form (like division by zero or \( \frac{0}{0} \)), the limit can be computed directly.

### Conclusion:
\[
\lim_{{x \to 3}} \frac{3x^2 - 8}{x - 2} = 19
\]
