If the function f(x) = 2x + 1, what is f(3)?

Explanation:
To determine \( f(3) \) for the function \( f(x) = 2x + 1 \), you simply substitute \( x \) with 3 in the expression. Start the process by plugging in the value of \( x \): \[ f(3) = 2(3) + 1 \] Next, multiply 2 by 3: \[ 2(3) = 6 \] Now, add 1 to the result: \[ 6 + 1 = 7 \] Thus, \( f(3) \) evaluates to 7. This demonstrates how to apply the function correctly by substituting the value of \( x \) and following the proper order of operations. The resulting value of 7 confirms that the calculation is performed accurately, leading directly to the correct answer.

To determine ( f(3) ) for the function ( f(x) = 2x + 1 ), you simply substitute ( x ) with 3 in the expression.

Start the process by plugging in the value of ( x ):

[

f(3) = 2(3) + 1

]

Next, multiply 2 by 3:

[

2(3) = 6

]

Now, add 1 to the result:

[

6 + 1 = 7

]

Thus, ( f(3) ) evaluates to 7. This demonstrates how to apply the function correctly by substituting the value of ( x ) and following the proper order of operations. The resulting value of 7 confirms that the calculation is performed accurately, leading directly to the correct answer.
