• -5 ≤ x ≤ -3
• -2 ≤ x ≤ 3
• -5 ≤ x ≤ 3

A toy rocket is launched into the air, and the data from the rocket's flight is graphed below. What is the domain of the data collected?

• 0≤ x ≤ 7
• 0≤ x ≤ 8
• 0≤ y ≤ 7
• 0≤ y ≤ 8

What is the range of the function graphed?

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

What is the range of the table?

• {-4, 0, 1, 3}

• {-2, 0, 2, 3}

• {-4, -2, 0, 1, 2, 3}

• { (0, 0), (2, -4), (3, 3), (-2, 1) }

Is the relation shown a function?

• No, because the x-value 11 is paired with 5 and 8.

• Yes, because each x-value has only one y-value paired with it.

Does the graph represent a function?

• Yes

• No

What is the domain?

• -4 < x ≤ 5
• -4 ≤ x < 5
• -3 < y < 3
• -3 ≤ y ≤ 3
