ok can you tell me if 3 is less than -3?
anonymous
  • anonymous
no its not

Ok 3 is not equal to or less than -3 so we don't want to use that domain.

−3 < x ≤ 3 This means that x a number is higher than -3 or equal to or less than 3
anonymous

is 3 higher than -3? Yes is it equal to 3? yes that's all we need.
anonymous
  • anonymous
that means we have to use f(x)= (9 − x^2) that means we have to plug in x=3 into that equation and see what you get.
