Question

how do I find the limit as x approaches 3 from the left
I x-3 I / (x-3)

the x-3 in the numerator is absolute value

Answer 1

\[\lim_{x \rightarrow 3^-} \frac{ \left| x-3 \right| }{ x-3 }\]

better view of it

Answer 2

you need to graph the equation. From graph you get that the function approaches -1 as x approaches 3 from left

Answer 3

how do you find it without the graph for example



(just an example)

I just never understood that part /:
