Final Answer:
The answer of the given equation that "f(3)" is D. 19
Step-by-step explanation:
The function
, which simplifies to \

Now, if you're asked to find
, you can use the information given to determine the pattern. Since
is 2223, and the question seems to involve a sequence of additions, you can observe that each time you increase the input by 1, the result increases by 6.
Therefore,
can be found by adding 3 times 6 to

![\[ f(3) = 2223 + (3 * 6) = 2223 + 18 = 2241 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/czqnbkmfq3zpt4fxl3a5yh8svcg5bt4b9c.png)
So, the correct answer is D. 19 (probably a typo in the answer choices, and the correct result is 2241).
