Hint, To find domain, we know that the number inside the root should be greater then or equal to 0. So apply the condition that 9-x2>=0, this will give that -3<=x<=3, this is domain. Now to find the range. from the domain when x=0 output is 3 and when x is +/-3 output is 0. Therefore the output will range from 0 to 3. Thanks.
