@zepdrix I NEED YOUUU AGAIN!!! LOL

zepdrix · Answer

So the trick with determining limits from a graph is...
always look at the line, not the bubble.

f(2)=-1, the function is defined way down below.
But we don't care about the bubble.
We want to know, what y value is the line getting close to as we approach x=3 from the right.

zepdrix · Answer

I mean x=2*

anonymous · Answer

from the right it's getting close to 4 right? and from the left it's getting close to 1?

zepdrix · Answer

correct \c:/

anonymous · Answer

so how do I know which one should be the answer? bahahaha do you always use the rightside? @zepdrix

zepdrix · Answer

Oh my bad.

$$\Large \lim_{x\to2^+}f(x)$$See the little tiny plus sign in the exponent position?
That's telling you to approach from the right.
