What is the domain of the graph of the radical function?

• (-infinity, infinity)

• (-7, infinity)

• (0, infinity)

• (4, infinity)

Match the correct equation with the given graph.

• y = √(x - 3)

• y = √(x) + 3

• y = √(x + 3)

• y = √(x) - 3

• Step 1: subtract both sides by 8
• Step 1: add 6 to both sides
• Step 1: Divide both sides by 8
• Step 1: Divide both sides by 6

• A
• B
• C
• D

• x = 6, x = -1

• x = -6, x = 1

• x = 1

• x = 6

• Step 1: divide both sides by 2
• Step 1: add 9 to both sides
