Sketch the following polynomial function using the fourstep
     Sketch the following polynomial function using the four-step process.  f(x) = - 1/3 x (x^2 - 36)^2  The left-hand behavior starts  and the right-hand behavior ends.  Find the y-intercept.  The y-intercept is  . 
  
  Solution
f(x)=-1/3x(x2-36)2
To find the y intercept we have to plug x =0
f(0)=-1/3*0(0-36)2=0
Therefore y intercept is (0,0)
