domain of f(x)=

Question

sqrt(10-x)

Answer 1

Domain :

The function is f(x) = sqrt(10 - x).

The expression is √(10 - x) and (10 - x) should be zero or positive.

 (10 - x) ≥ 0

10 ≥ x.

The domain is all values of x such that x less than or equal to 10.

The interval notation form of domain is (- ∞, 10].
