Answer:
216 + 9i
Step-by-step explanation:
Given: f(x) = 3x² + 3 + 3x
When x = -9, f(x) equals to;
3(-9)² + 3(-9 + 3(-9)
243 + 3(3i) - 27
243 + 9i - 27
216 + 9i

The function is a continuous function at 2 if the LHL and RHL will be the same as the limit of the function.
<h3>What is continuity of a function?</h3>It is defined as the property of a function in which the function varies continuous, and we plot the graph of a function it doesn't break.
We have a function:
If f(x) is a continuous, then it will follow:
f(2) = 2² - 2 = 4 - 2 = 2
Left-hand limit at 2 = right-hand limit at 2 = 2
Limit at 2 of a function = 2
Using limit, we can check the whether the function is differentiable or not.
Thus, the function is a continuous function at 2 if the LHL and RHL will be the same as the limit of the function.
