Discover characteristics of piecewise functions that are not possible with single-formula functions.

			This function is discontinuous at x=0 because the left and right hand limits as x→0 do not equal the value of the function, 1. The discontinuity is called removable because the discontinuity can be removed by redefining f at x=0.
