we can check each option using the limit number f(x)=3 and a number out of the range(4)
must have a value for the limit number but a mistake when we use 4
A.
f(x)=3
any value of x will result in 0
then A is wront because dont have a solution for the limit number
B.
f(x)=3
has a solution for f(x)=3
f(x)=4
has a solution for a value out of the range then option B is wrong
C.
f(x)=3
has a solution for f(x)=3
f(x)=4
root of negative number doesnt have real solution , then this fuction dont have solution for a number out of the range
Option C is RIGHT because has solution on the limit number f(x)=3 but not a solution for a number out of range
