• Not a Function

CCSS.8.F.A.1

Does the graph represent a function?

• Yes, because the vertical line test touches only one point at a time.

• No, because the vertical line test touches more than one point at a time.

All of the x-values (inputs) are called what?

• Domain

• Range

All of the y-values (outputs) are called what?

• Domain

• Range

Any set of ordered pairs is called what?

• the domain

• a relation

• a function

• the range

What is the range of the mapping?

• {1, 2, 4}

• {0, 1, 2, 3}

• {0, 3}

• {1, 4}

What is the domain 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 up twice (5 and 8)

• Yes, because each x-value is used only once

Why is the following relation NOT a function?

(2, 3), (4, 9), (3, 8), (4, 15)

• Because the numbers are not least to greatest

• Because 3 is repeated

• Because 4 is repeated in the domain

• Because there are no negatives

What is the test to determine if a graph represents a function?

• Horizontal line test

• Vertical line test

• Heidelberg Uncertainty Test

• Obi Wan Kenobi Test
