Answer :
To solve the problem of finding [tex]\( F(4) \)[/tex] using the function [tex]\( F(x) = 3x \)[/tex], follow these steps:
1. Understand the Function: The function given is [tex]\( F(x) = 3x \)[/tex]. This means for any input [tex]\( x \)[/tex], the output is 3 times that input.
2. Substitute the Value: We need to find [tex]\( F(4) \)[/tex]. Substitute [tex]\( x = 4 \)[/tex] into the function.
3. Perform the Calculation:
[tex]\[
F(4) = 3 \times 4
\][/tex]
4. Multiply: Calculate the multiplication:
[tex]\[
F(4) = 12
\][/tex]
5. Final Answer: The value of [tex]\( F(4) \)[/tex] is 12.
Therefore, the correct answer is B. 12.
