Answer:
Option D
Explanation:
x is given to be 4 in this case, so all we would have to is plug it into the following function -
Through substitution, you would receive the following function -
![f ( x ) = \left \{ {{2, 4 < 4 } \atop 6, 4 \geq 4 }} \right](https://img.qammunity.org/2021/formulas/mathematics/college/kej88n2nq3hz1frxihseqigi0icl4ixdfd.png)
Now the graph proves that this function is closer to 4, and thus proves that the y - coordinate is about 2 at the same time. However, the graph is cut off, so the limit doesn't exists.
