    \[\lim_{h \rightarrow 0} \frac{|7h|}{h}\] Is that it?

    Basically, you have to split it into two, but if h is approaching zero, then that means the limit doesn't exist

    Because it will be approaching a different value from the left and a different value from the right

    Oh, wait, no, it's from the left, not the overall limit. -7 is right.
