Question: What is the domain of the graphed function?
A) x>1
B) x≥1
C) x>3
D) x≥3
Answer: B) x≥1
Explanation:
Step 1: Identify the function's domain
The graph starts at x=1 and extends to the right. This indicates that the function is defined for all x values greater than or equal to 1.
Step 2: Understand inequality notation
The inequality x≥1 means x is greater than or equal to 1, matching the graph's behavior.

Question What is the domain of the square root function graphed below?
A) x≤−1
B) x≥−1
C) x≤0
D) x≥0
Answer: B) x≥−1
Explanation:
Step 1: Determine the starting point
The square root function begins at x=−1 and extends to the right. The square root function is undefined for values less than −1.
Step 2: Apply inequality constraints
The inequality x≥−1 corresponds to the graph, where x includes −1 and all larger values.
