The answer is: "1" .
From the graph, we see that as "x" approaches "3" from the "left-hand side", the "y-value" ; or f(x) ; (that is, the output) approaches: "1" .
Note: The "left-hand side" , in this case, refers to the values of "x" LESS THAN "3" , as indicated in the "3⁻ " in this "limit problem".
