this is how you plug it in: [(x + Δx)^2 + 1- (x^2 + 1)]/(Δx) Rework the equation to get: Δx + 2x, in it should be lim as Δx goes to 0, and that would leave you with 2x, which if you used easy method, leaves you with same answer.

The answer is 3 (choice E). If 3n-4=n+2... you need to breakdown the equation. Add 4 to both sides. So that leaves you with 3n=n+6. Subtract 1n from both sides. So that leaves you with 2n=6. Divide both sides by 2... therefore n=3.
