find the domain and all the critical points of the function.
a) x(the square root of 94-x^2)

The domain is x must be less than or equal to positive or negative two but when i go to do the derivative to find the critical points i always get stuck. can someone show me step by step?

  • math -

    f(x) = x√(94 - x^2)

    domain: -√94 ≤ x ≤ √94

    (looking at your answer of -2≤x≤2, I think that 9 was supposed to be a ( , is that right ?)
