Answer :
Final answer:
To find F(3) for the function F(x) = 3x, you replace x with 3 and get F(3) = 3(3), which equals 9.
Explanation:
To find F(3) using the function F(x) = 3x, you simply substitute the value of x with 3. This is a straightforward evaluation of a function for a given input.
Here are the steps:
- Start with the function definition: F(x) = 3x.
- Replace every occurrence of x with 3: F(3) = 3(3).
- Multiply the numbers: F(3) = 9.
Therefore, F(3) is 9, which corresponds to option B.
