• Function
• Not a Function

CCSS.8.F.A.1

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values
• No, because the vertical line test shows there are repeating input values

CCSS.8.F.A.1

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and the range

• D: {1, -3, -4,}

  R: {0, 1, 2, -4}

• D:{0, 1, 2, -4}

  R:{1, -3, -4}

• D:{0, 1, 2, 3, 4}

  R:{1, -3, -4}

What is the range of the graph?

• 1 ≤ x ≤ 5

• 1 < x < 5

• 1 ≤ y ≤ 5

• 1 < y < 5

What is the domain of the graph?

• -7 ≤ x < 5

• -3 ≤ x < 1

• -3 ≤ y < 1

• -7 ≤ y < 5

What is the range?

And an open circle means it DOES NOT equal that number - use < and >

Only use ≤ and ≥ with a closed circle.

• -4 < x ≤ 5

• -4 ≤ x < 5

• -3 < y < 3

• -3 ≤ y ≤ 3

What is the DOMAIN of this graph?

• x < -3

• x ≤ -3

• x > -3

• x ≥ -3

Michael run a mile about every 10 minutes.  Is this discrete or continuous data?

• Discrete
• Continuous
