Task

Plot a function represented as     x,  y     numerical arrays.

Post the resulting image for the following input arrays (taken from Python's Example section on Time a function):

      x = {0,   1,    2,    3,    4,    5,     6,     7,     8,     9};
      y = {2.7, 2.8, 31.4, 38.1, 58.0, 76.2, 100.5, 130.0, 149.3, 180.0};

This task is intended as a subtask for Measure relative performance of sorting algorithms implementations.
