I'm stuck on this one problem and I reading my text book but i stilll don't get function and d... the problem says ..

anonymous · Answer

for the function f whose graph is given state the value of each quanity if it exists. if it does not exist explain why the first  graph is lim f(x) x arrow 1 ???

anonymous · Answer

do you mean:

$$\lim_{x \rightarrow 1} f(x)$$

anonymous · Answer

yes

anonymous · Answer

how do you solve these kind of prolems

anonymous · Answer

do you have the graph? or did they give you what f(x) was

anonymous · Answer

yes I have a graph

anonymous · Answer

there are three points at three

anonymous · Answer

ok. well it's basically asking you what happens on the graph when x is approaching 1.

so you can just go ahead and plug in x=1 and see what that is on the graph.

anonymous · Answer

so if you plug in x=1 and there's a point there on the graph, then the value exists.

if you plug in x=1 and there is no point there, then the value does not exist.
