title: python plotting graph with float input variables
body: <p>I want to ask about python plotting matplotlib.pyplot graph
  For example,
  If mu function is like
  y1 = ax<em>b+c</em>d
  y2 =a**2+bx+c*d
  then x in range of 0 to 10
  how to plot graph if my a,b,c need own number such as</p>
  <pre><code>a = float(input('Enter a:'))
  b = float(input('Enter b:'))
  c = float(input('Enter c:'))
  </code></pre>
  <p>y1 and y2 also need plot in same graph</p>
