What is the limit of f(x) = x - 4 as x approaches 3?

To find the limit of the function ( f(x) = x - 4 ) as ( x ) approaches 3, we can evaluate the function by directly substituting 3 into it.

When we substitute ( x = 3 ) into the function, we get:

[

f(3) = 3 - 4 = -1

]

Therefore, as ( x ) approaches 3, the value of ( f(x) ) approaches -1. This means the limit of the function as ( x ) approaches 3 is -1.

The correct answer reflects this evaluation, confirming that the limit is indeed -1 when substituting the value of ( x ).
