Question 198056
compute the following limit:
lim x^2+x-12/x-3
x->3
---------------------
Factor to get [(x+4)(x-3)/(x-3)]
= (x+4)
---------------------
Take the limit as x goes to 3
-----
limit = 7
-------------------------------------
You can see this in the graph:
{{{graph(400,300,-10,10,-10,10,(x^2+x-12)/(x-3))}}}
