Find limit as x approaches -1 (x^2+2x+3)/(x^2+1)
A. 0
B. 1
C. Infinity
D. DNE
E. None of these
Step 1 of any limit question for me is to sub in the approach value.
I that turns out to be a real number, that is your answer, all done!
so when x = -1
your expression = (1-2+3)/(1+1) = 2/2 = 1
looks like B to me
