Find the limit of f(t) using its graph.

Exercise:

In question c, the answer is does not exist because "As t approaches 0 from the left, f(t) approaches -1 and as t approaches 0 from the right, f(t) approaches 1".
The solution above is from Thomas-Calculus 13th edition.

I can not understand the order... Why f(t) approaches -1 from the left and not the opposite?

To me it seems the opposite. As f(t) approaches 0 from the left, f(t) approaches 1 and as t approaches 0 from the right, f(t) approaches -1.
