If f(x) = 3x + 7, what is the value of f(2)?

If f(x) = 3x + 7, what is the value of f(2)?

• A. 10
• B. 11
• C. 13
• D. 15

Answer: (C)

To determine the value of \( f(2) \) given the function \( f(x) = 3x + 7 \), you need to substitute \( 2 \) for \( x \) in the equation. This means calculating \( f(2) \) as follows: 1. Start by replacing \( x \) with \( 2 \) in the function: \[ f(2) = 3(2) + 7 \] 2. Perform the multiplication: \[ 3(2) = 6 \] 3. Then, add \( 7 \) to \( 6 \): \[ 6 + 7 = 13 \] Therefore, the value of \( f(2) \) is \( 13 \). This confirms that the correct answer is indeed 13, as it results directly from the calculations based on the defined linear function.

To determine the value of ( f(2) ) given the function ( f(x) = 3x + 7 ), you need to substitute ( 2 ) for ( x ) in the equation. This means calculating ( f(2) ) as follows:

1. Start by replacing ( x ) with ( 2 ) in the function:

[

f(2) = 3(2) + 7

]

2. Perform the multiplication:

[

3(2) = 6

]

3. Then, add ( 7 ) to ( 6 ):

[

6 + 7 = 13

]

Therefore, the value of ( f(2) ) is ( 13 ). This confirms that the correct answer is indeed 13, as it results directly from the calculations based on the defined linear function.
