Using the graph given to us here, we want to find the specified limits or otherwise state that it does not exist. Now our first limit here is a left sided limit, the limit of f of x as x approaches 0 from the left. Now coming in from that left side approaching that value of 0, I see that my function is coming close to a value of 0 as well. Now from that right side, my right sided limit as x approaches 0 from the right, I see that again my function is kind of closing in and getting really close to this value of 0. Now since these two limits, my one-sided limits from the left and the right, are equal to each other, I already know what my limit of f of x as x approaches 0 is. It's that same value of 0. Now again here, reminder that it does not matter what the value of our function is at 0, just what our function is doing as x gets really, really close to 0. Thanks for watching, and I'll see you in the next one.

Verified step by step guidance

Observe the graph of the function f(x) and identify the behavior of the function as x approaches 0 from the left (x -> 0^-). Notice that the graph approaches the y-value of -1 as x approaches 0 from the left.

Next, examine the behavior of the function as x approaches 0 from the right (x -> 0^+). The graph also approaches the y-value of -1 as x approaches 0 from the right.

Since both the left-hand limit and the right-hand limit as x approaches 0 are equal to -1, we can conclude that the two-sided limit exists and is equal to -1.

Therefore, the limit of f(x) as x approaches 0 is -1, which means lim_{x$\rightarrow$0}f(x) = -1.

In summary, the limits are: lim_{x$\rightarrow$0^{-}}f(x) = -1, lim_{x$\rightarrow$0^{+}}f(x) = -1, and lim_{x$\rightarrow$0}f(x) = -1.
