  1. the graph can be seen here:

    http://www.wolframalpha.com/input/?i=plot+y%3D|x^2+%2Bx-2|+for+-4+%3C%3D+x+%3C%3D+3

    That should make it easy to answer the other questions. If not, come on back and show where you get stuck.

  2. I think we went through this before.
    note I think the somewhat unusual exponent notation may mean
    | x^2 + x^-2| = | x^2 + 1/x^2 |

  9. Calculus

    For the function below, determine the intervals of concavity: f(x)=xlnx I tried doing it but the second derivative would always be f''(x)=1/x, so it would be concave up at x>0 and concave down at x
