Determine whether the three points are collinear.
-Which one is the graph of $y = \sqrt { x }$ ? What is it's domain?
A) graph $A ; ( - \infty , \infty )$
B) graph D; $[ 0 , \infty )$
C) graph $C ; \{ - 2 , - 1,0,1,2 \}$
D) graph B; $[ 0 , \infty )$

Question

Quizplus · Accepted Answer

The graph of $y = \sqrt{x}$ only includes non-negative x-values because you cannot take the square root of a negative number in the real number system. This means its domain is $[0, \infty)$. Graph D correctly represents this function and its domain.
