Use an algebraic technique to evaluate the limit below. Which technique did you use, and what limit did you find? lim 2-1 23 +2x - 3x x+8x-9 Using "direct substitution", the limit does not exist. Using "multiply by the conjugate", the limit is 2/5. Using "factor and cancel", the limit is 0. Using "factor and cancel", the limit is 2/5.
