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 ?)

For nth root functions, I know that if "n" is even, then the domain must be equal or greater than zero. If "n" is odd, then domain will be all set of real numbers. But how do I determine the range of an n-th root function?
