Domain and Range

What is the DOMAIN?

• One way to think about the Domain is how far the graph extends left and to right along the x-axis. "How far does the graph reach to the left and right along the x-axis number line?"

• (-4, ∞)

• [-3, 3)

• (-3, 3]

What is the RANGE?

• {-3, 3]

• all real numbers

• [-4, 5]

• One way to think about the Range is how far the graph extends down and up along the y-axis. "How far does the graph reach down and up along the y-axis number line?"

What is the RANGE?

• (-∞, 0)

• (0, ∞)

• All real numbers

• One way to think about the Range is how far the graph extends down and up along the y-axis. "How far does the graph reach down and up along the y-axis number line?"

What is the DOMAIN?

• [0, ∞)

• (-∞, 0)

• All real numbers

• One way to think about the Domain is how far the graph extends left to right along the x-axis. "How far does the graph reach to the left and right along the x-axis number line?"

What is the Range?

• y ≥ 6

• y ≤ 6

• -10 ≤ y ≤ 6

• One way to think about the Range is how far the graph extends down and up along the y-axis. "How far does the graph reach down and up along the y-axis number line?"

What is the DOMAIN of this graph?

• -7<x<5

• -7≤x<5

• -3<y<1

• One way to think about the Domain is how far the graph extends left to right along the x-axis. "How far does the graph reach to the left and right along the x-axis number line?"

What is the Domain of the graph?

• {xI -5 < x ≤ 1}

• {xI -5 < x < 1}

• {xI -5 ≤ x ≤ 1}

What is the range of the graph?

• {y I -4 ≤ y ≤ 3}

• {y I -4 ≤ y < 3}

• {y I -4 < y < 3}

• One way to think about the Range is how far the graph extends down and up along the y-axis. "How far does the graph reach down and up along the y-axis number line?"

What is the domain of the graph?

• x > - 2
