What is f(12) if f(x) = 3x?
Understand the Problem
The question is asking to find the value of the function f(12) given the formula f(x) = 3x. To solve this, we will substitute 12 into the formula and calculate the output.
Answer
The value of \( f(12) \) is \( 36 \).
Answer for screen readers
The value of ( f(12) ) is ( 36 ).
Steps to Solve
- Substituting the value into the function
We start by substituting ( x = 12 ) into the function ( f(x) = 3x ).
- Calculating the output
Now, calculate ( f(12) ): $$ f(12) = 3 \times 12 $$
- Final calculation
Perform the multiplication: $$ f(12) = 36 $$
The value of ( f(12) ) is ( 36 ).
More Information
The function ( f(x) = 3x ) is a linear equation where each input ( x ) is multiplied by 3. Thus, if we input 12, the output is simply three times that value.
Tips
- Forgetting to multiply by the coefficient of ( x ).
- Confusing the order of operations (always multiply first in this case).
