$f(x)$ is plotted below. List all real values of $x$ for which $f(x)$ is discontinuous. Separate values with commas. Enter $\text{NONE}$ if there are no such values.



Hint 1: We are looking for all real of $x$ at which there are removable, jump, and infinite discontinuities on the graph of $f(x)$.
Looking at the graph, we see that $f(x)$ is discontinuous at:
