Question

Determine the domain of the function. f as a function of x is equal to the square root of one minus x. All real numbers x > 1 x ≤ 1 All real numbers except 1

Answer 1

x ≤ 1

Explanation:

For f(x) = √(1 -x), the function is defined where the square root is defined:

1 -x ≥ 0

1 ≥ x . . . . . add x

The domain is x ≤ 1.
