what is the domain of the square root function graphed below?\no x≥ - 4\no x> - 4\no x≥0\no x>0
Answer
Answer:
A. $x\geq - 4$
Explanation:
Step1: Recall domain definition
The domain of a function is the set of all possible x - values.
Step2: Identify left - most x - value
The left - most point of the square - root function graph is at $x=-4$.
Step3: Determine domain type
Since the graph includes the point at $x = - 4$ (the dot is filled), and extends to the right, the domain is $x\geq - 4$.
