​Relations

Multiple Choice

What is the definition of function?

• Has inputs and outputs
• Every input (x-value) has only ONE output (y-value)

• Inputs have different outputs every time
• x-values and y-values

Multiple Choice

All of the y values or outputs are called what?

• Domain
• Range
• Relation
• Function

Multiple Choice

All of the x values or inputs are called what?

• Domain
• Range
• Relation
• Function

Multiple Choice

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

• D: {-4, -3, 1}
  R: {0, 1, 2, -4}
• D:{-4, 0, 1, 2}
  R:{1, -3, -4}
• D:{0, 1, 2, 3, 4}
  R:{1, -3, -4}

Multiple Choice

• {-7, -5, 2, 3, 7}
• {-7, 7}
• {1, 2, 3, 4, 5}
• {1, 5}

Multiple Choice

• {1, 2, 3, 4, 5}
• {-1, 1, 2, 3}
• {1, 2, 3, 5}
• {1, 5}

Multiple Choice

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.

Multiple Choice

Is this mapping a function or not a function? 

• Function
• Not a Function 

Multiple Choice

• A
• B
• C
• D

Multiple Choice

What is the correct Form for standard form?

• y =mx + b

• y- y = m(x -x)

• Ax + By = C

Multiple Select

Select all that are linear

Multiple Choice

What is the y-intercept?

• (0,7)
• (0, 0)
• (0,1)
• (0, 2)

Multiple Choice

• Function
• Not a Function

Multiple Choice

Is this graph a function or not a function? 

• Function 
• Not a Function

Multiple Choice

Multiple Choice

What is the meaning of the y-intercept?

• The weight in the bucket increases by 1 pound per pound of sand.
• Before sand is put in the bucket, it weighs 1 pound.
• The starting weight of the sand is 1 pound.
• The weight in the bucket decreases by 1 pound per pound of sand.
