  Sketch the following graphs.

   

  y = | 9 - x^2 |

   

  my corresponding range of values of y is y > or equal to 0. Ain't sure about this. Could someone help?

   

  and the next question.

   

  y = |(2x +1)(x-2)|

  corresponding range of values of y is is same as above, y is equal or more than 0.

   

  Please help me check if there's any mistakes.
