Question

Find the limit of the function (if it exists). Write a simpler function that agrees with the given function at all but one point.

lim x->-1 (2x^2 - x - 3)/(x+1)

Answer 1

HINT factor (2x^2 - x - 3)

Answer 2

another hint, since you know you get 0 if you replace \(x\) by \(-1\) you know it must factor as \[2x^2-x-3=(x+1)(\text{something})\]
