Practice with functions

What is the range of the graph shown?

• 3 < x ≤ 6
• -6 < y ≤ 3
• -2 < y ≤ 6
• -2 < x ≤ 6

What is the domain of the graph shown?

• -2 < y ≤ 6
• -6 ≤ x < -2
• -6 < y ≤ 6
• -6 < x ≤ 3

What is the range of the relation shown in the graph above?

• {2, 0, 3, -1, 5}
• {0, 1, 3, -2, -5}
• {-2, 2, -1, 5, 3}
• {2, 0, -1, -5, 3}

Does this mapping represent a function? Why or why not?

• Yes, this is a function because all the x values are different.
• No, this is not a function because not all the x values are different.
• Yes, this is a function because all the y values are different.
• No, this is not a function because not all the y values are different.
