2x3 + 2x + 1 6. (10 points) Find all asymptotes of y = x2 - 5x + 6 7. (10 points) Two runners start a race at the same time and finish in a tie. Prove that at some time during the race they have the same speed. Hint: Try to make a connection between this problem, and one of the important theorems you learned in this course! When you want to use the relevant theorem, make sure that you will explicitly check all the conditions of the theorem
