Homework on 30 January 2016:

To be turned in on Monday:
  1. For what values of $k$ is $$ f(x) = \cases{x^2+2kx+k^2& \text{for $x<-1$}\\[3px] 4k-x& \text{for $x\ge -1$}\cr} $$ continuous at $x=-1$?

    Fully justify your answer (for instance, you might want to show that, for your value(s) of $k$, $f$ statisfies the definition of continuity at $x=-1$. Make sure you give reasons for all of your claims.)

  2. Compute the derivatives of the following function: $f(x) = (x^2-3x)e^{-x^2}$
