Question

What is the domain of the function y=2 square root x-5.

Answer 1

x ≥ 5

Step-by-step explanation:

so, we have

y = 2√x-5

We know that the radicand (number under a radical) must be greater than or equal to zero so, we set up the equation as

x - 5 ≥ 0

to solve it, we add 5 to both sides and you get

x ≥ 5

the domain is the interval---> [5,∞)

All real numbers greater than or equal to 5
