All real numbers but 3 and -3
Answer:
-1/9
Step-by-step explanation:

For simplicity, let's multiply top and bottom by 3x:

Factor out a -1:

Divide top and bottom by x−3:

Evaluate the limit:

It's important to note that the function doesn't exist at x = 3. As x <em>approaches</em> 3, the function <em>approaches</em> -1/9.
Answer:
B
Step-by-step explanation:
To evaluate f(2) substitute x = 2 into f(x), that is
f(2) = - (2)³ + 2(2)² - 3 = - 8 +2(4) - 3 = - 8 + 8 - 3 = - 3
