    think..what does f(x) "want" to be as you approach 3 from the left side?

    what's the y value at x=3, if you're coming up the line from the left side?

    no.. what you want to do is check f(x) for values close to x=3, but coming at it just slightly on the left side. That's what the x->3- means.. the - means come at x=3 from the left side.

    it's ok.. imagine traveling along the line of the graph from left to right, kind of sneaking up to where x=3 The thing about a limit is that you don't actually care about the y-value AT x=3, you only care what that y-value is approaching as you get closer and closer. So looking at the graph, if x is say, equal to -2, then what is y?

    ok so we are looking at the y-value as x approaches 3 from the left
