1. The problem statement, all variables and given/known data Show that the following function is contractive on the indicated intervals. Determine the best values of [lamda] in Equation (2). abs(x)^(2/3) on abs(x) < or = 1/3 2. Relevant equations A mapping (or function) F is said to be contractive if there exists a number [lamda] less than 1 such that: (Equation (2)) abs(F(x)-F(y)) < or = [lamda]*abs(x-y) for all points x and y in the domain F. 3. The attempt at a solution I'm not really sure what to do with this one or how to get [lamda] in this case.
