    move to x = 60 on the graph curve then move slightly to the left of x = 60. Approach x = 60 and get closer and closer. What y value are you getting closer to?

    so you now see how I got \[\Large \lim_{x \to 60^{-}}f(x) = 56\] ??

    ok let's try another limit, like \[\Large \lim_{x \to 40^{-}}f(x)\] what is the value of this left hand limit?

    find x = 40 on the x axis then slightly move to the left of x = 40 jump up to the function curve and get closer and closer and closer to x = 40 itself which y value are you getting closer to?

    hopefully we're still on the same page you're using this graph right? http://assets.openstudy.com/updates/attachments/55dfa1f2e4b0819646d755f0-tazmaniadevil-1440719400575-screenshot_2.png

    ok, if you were to draw a vertical line through x = 40, where does this vertical line hit the graph?

    and if you went slightly to the left, say to x = 38, where does the vertical line cross the function?

    it sounds like you're not sure how to read a graph? or how to evaluate a function? I'm not exactly sure where you're stuck
