# Math Help - Inequality/limit

1. ## Inequality/limit

For this graph http://img97.imageshack.us/img97/6213/graph.png,

I need to find the set of all values of $a$ that make the following inequality true, Limit as x approaches a- for f(x) $\leq$f(a)

2. As you approach any of those solid dots from the left, you'll be approaching from the segment directly below it, until you get to x > 1, at which point the segments are above the dots.

So I think they're asking for the x-values of the dots, but only for x < 1.

3. I'm to put the values into interval notation,
What i have is (-4,-3)U(-3,-2)U(-2,-1) etc. ,however i'm doing something wrong
