title: Generate an array of random values from a created function to be plotted
body: <p>I have a function:</p>
  
  <pre><code>f = x**0.5*numpy.exp(-x/150)
  </code></pre>
  
  <p>I used numpy and matplot.lib to generate a plot of f as a function of x with x:</p>
  
  <pre><code>x = np.linspace(0.0,1000.0, num=10.0)
  </code></pre>
  
  <p>I am wondering how do I create an array of random x values would create the same plot for this function using the x array I first made?</p>
