Verified by Toppr. Indeed, you can start from x 0 ), so x 2 0 for all x ≠ 0, we can multiply through by x2 to get. Prove lim_(x->-2)(x^2-1)=3 Work (not part of proof): 0<|x+2|< delta; |(x^2-1)-3|< epsilon We need to manipulate the |(x^2-1)-3|< epsilon to show that |x+2|<"something" to set delta equal to that term: |(x^2-1)-3|< epsilon |x^2-4|< epsilon |(x+2)(x-2)| < epsilon |x+2| < epsilon/(x-2) Since we cannot have a x term with epsilon, we let delta = 1 and solve for the value x+2 would be: 0
