Question #38830

Answer 1

Normally, in the real domain, `f(x) = sqrt(25-x^2)` is meant to be the positive value of the root.

Explanation:

The Mean Value Theorem applies to a single valued real function, so in this case, `f(3) = 4` satisfies the MVT for the function `f(x) = abs sqrt(25-x^2)` and `f(3) = -4` satisfies the MVT for the function `f(x) = -abs sqrt(25-x^2)`
