If f(x) = 2x + 3, what is f(4)?

Explanation:
To determine the value of \( f(4) \) when given the function \( f(x) = 2x + 3 \), you substitute \( x \) with \( 4 \). Start by substituting \( 4 \) into the function: \[ f(4) = 2(4) + 3 \] Calculate \( 2(4) \): \[ 2(4) = 8 \] Now, add \( 3 \): \[ 8 + 3 = 11 \] Thus, \( f(4) \) evaluates to \( 11 \). This shows that the correct answer is indeed \( 11 \). The process of substitution into the function and performing the arithmetic step-by-step confirms the result.

To determine the value of ( f(4) ) when given the function ( f(x) = 2x + 3 ), you substitute ( x ) with ( 4 ).

Start by substituting ( 4 ) into the function:

[

f(4) = 2(4) + 3

]

Calculate ( 2(4) ):

[

2(4) = 8

]

Now, add ( 3 ):

[

8 + 3 = 11

]

Thus, ( f(4) ) evaluates to ( 11 ). This shows that the correct answer is indeed ( 11 ). The process of substitution into the function and performing the arithmetic step-by-step confirms the result.
