Introduction to Graphs and Functions

What letter is located at (8, 5)?

• A

• B

• C

• D

In the ordered pair (4,9), which number is the y-coordinate?

• 4

• 9

• neither

• both

The right grouping in a mapping is the...

• domain.

• range.

• x-axis.

• coordinate system.

• {-2, 3, 7}

• [-2, 3]

• {1, 2, 2, 3, 4}

• [1, 4]

• {1, 2, 3, 4, 5}

• {-1, 1, 2, 3}

• {1, 2, 3, 5}

• [1, 5]

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) }

In the given relation, what domain value corresponds to the range value -2?
{(-1,2), (-2,4), (2,5), (0,-2), (2,0)}

• -2

• 0

• 2

• 4

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

• D: {1, -3, -4,}

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

• D:{-4, 0, 1, 2}

  R:{-4, -3, 1}

• D:{0, 1, 2, 3, 4}

  R:{1, -3, -4}

What is the type of the relation?

• One-to-one relation

• One-to-many relation

• Many-to-one relation

• Many-to-many relation

What is the range?

• the set of all x-values

• the set of all y-values
