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

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.
