what is the domain of the function y = √x?\n-∞ < x < ∞\n0 < x < ∞\n0 ≤ x < ∞\n1 ≤ x < ∞
Answer
Answer:
C. $0\leq x<\infty$
Explanation:
Step1: Recall domain - square root rule
The expression inside square - root $\sqrt{x}$ must be non - negative.
Step2: Set up inequality
We set $x\geq0$.
Step3: Write domain in interval notation
The domain of $y = \sqrt{x}$ is $[0,\infty)$ or $0\leq x<\infty$.
