Question

VERTICAL STRETCHES AND SHRINKS OF THE SQUARE ROOT FUNCTION

What is the domain of the function f(x) = Vo?
O all real numbers
O all real numbers less than 0
all real number less than or equal to 0
O all real numbers greater than or equal to 0

Answer 1

all real numbers greater than or equal to zero

Explanation:

The domain of the real function f(x) = sqrt(x) is

all real numbers greater than or equal to zero

because when x < 0, then f(x) will become complex, which does not belong to a real function.
