Question
Let \( f(x) = \sqrt{30 - x} \) and \( g(x) = x^2 - x \).

Then the domain of \( f \circ g \) is equal to \([a, b]\) for

\[ a = \, \, \]

and 

\[ b = \, \, \]

**Explanation:**

- This problem involves two functions, \( f(x) \) and \( g(x) \).
- The function \( f(x) = \sqrt{30 - x} \) requires that \( 30 - x \geq 0 \), which implies \( x \leq 30 \) for the domain.
- The function \( g(x) = x^2 - x \) is a quadratic function, and for the composition \( f(g(x)) \) to be defined, the output \( g(x) \) must be within the domain of \( f(x) \).

The objective is to find the range of \( x \) values such that when \( g(x) \) is plugged into \( f(x) \), it results in a defined expression. Once this range is determined, the values of \( a \) and \( b \) can be filled in accordingly.
