Problem 01 to 05: Finding Limits

Problem
Evaluate the limit of the following.

  1. lim
     
  2. \displaystyle \lim_{x \to -1} (2x^2 + x + 4)
     
  3. \displaystyle \lim_{y \to 3} (y^3 - 2y + 7)
     
  4. \displaystyle \lim_{y \to -2} (y^3 + 5y - 1)
     
  5. \displaystyle \lim_{t \to 0} \dfrac{2t^2 + 1}{t^3 + 3t - 4}
