Answer :

To find F(3) for the function F(x) = 3x, we substitute 3 for x, resulting in 3(3) which equals 9. Therefore, the correct answer is B. 9.

The question asks us to find the value of F(3) given the function F(x) = 3x. To find F(3), we replace x with 3 in the function, leading to the equation F(3) = 3(3). Calculating this gives us 9 as the result, making the correct answer choice B.

Final answer:

To find F(3), substitute 3 into the function F(x) = 3x. The answer is 9.


Explanation:

To find F(3), substitute 3 into the function F(x) = 3x. So, we have F(3) = 3(3) = 9.
