Now try an example that isn't trivial.  Let

:<math>f(x) = x^x\,</math>

:<math>f(x) = x^x\,</math>

This function is well-defined for x>0, using the general definition that involves the [[exponential]] and [[natural logarithm]] functions.  But we can calculate f(x) for other values:

This function is well-defined for x>0, using the general definition that involves the [[exponential]] and [[natural logarithm]] functions.  We can calculate f(x) for various values of x:

  f(5) = 3125

  f(5) = 3125

  f(2) = 4

  f(2) = 4
