Observe the graph of the function f(x) around x = 0. Notice that as x approaches 0 from the left (x -> 0^-), the function f(x) approaches the y-value of 0.
Similarly, as x approaches 0 from the right (x -> 0^+), the function f(x) also approaches the y-value of 0.
Since both the left-hand limit and the right-hand limit as x approaches 0 are equal to 0, the two-sided limit lim_{x->0}f(x) also exists and is equal to 0.
Therefore, we can conclude that lim_{x->0^-}f(x) = 0, lim_{x->0^+}f(x) = 0, and lim_{x->0}f(x) = 0.
The correct answer is: lim_{x->0^-}f(x) = 0, lim_{x->0^+}f(x) = 0, and lim_{x->0}f(x) = 0.
