Solution Steps

To find the values of the limits and the function at x=3, we need to analyze the behavior of the function as x approaches 3 from the left and from the right. We also need to determine the value of the function at x=3.

Step 1: Determine the Limits

The limit from the left as \( x \) approaches 3 is 6, and the limit from the right as \( x \) approaches 3 is also 6. Therefore, the limit as \( x \) approaches 3 is \( \boxed{6} \).

Step 2: Calculate the Value of the Function at \( x = 3 \)

Substitute \( x = 3 \) into the function \( f(x) = \frac{x^2 - 9}{x - 3} \) results in an undefined value (nan) due to division by zero. Hence, the value of the function at \( x = 3 \) is \( \boxed{DNE} \).

Final Answer

\(\boxed{6}\), DNE
