Math Functions Review

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}

• D: {0, 1, 2, -4}

  R: {1, -3, -4, 1}

All of the y values or outputs are called what?

• Domain
• Range
• Relation
• Function

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

What is the definition of function?

• Has inputs and outputs (Has X and Y Values)

• Every input has only ONE output (Only One X-Value for a Y-Value)

• Inputs have different outputs every time (Every X-Value gives you a Different Y-Value every time)

• x-values and y-values
