M10 - Functions

What is the definition of a function?

• Has inputs and outputs

• Every input has only ONE output

• Inputs have different outputs every time

• x-values and y-values

Which set of ordered pairs is a function?

• (9,5) (10,5) (9,-5) (10,-5)

• (3,4) (4,-3) (7,4) (3, 8)

• (6,-5) (7, -3) (8, -1) (9, 1)

• (2, -2) (5, 9) (5, -7) (1, 4)

Is the graph pictured a function?

• Yes because it's increasing

• No because it's not straight

• yes becauses it passes the vertical line test

• yes because it's in all four quadrants

Is the graph pictured a function?

• Yes

• No

Is this mapping a function or not a function?

• Function, each input has only one output

• Not a Function because -4 has two inputs

• Not a Function because inputs are negative and positive

• Not a function because there are only three outputs

Is this set of ordered pairs a function or not a function? 

• Function - each input has only one output

• Not a Function because -5 is listed twice

• Not a function because -2 is listed twice

• Not a function because there are negative outputs

All of the y values or outputs are called what?

• Domain

• Range

• Relation

• Function

All of the x values or inputs are called what?

• Domain

• Range

• Relation

• Function

Determine if the graph is a function or not. If yes, determine if it's linear.

• Function, non-linear

• Not a Function

• Function, linear

• Not a function, linear

Consider the function:{(3,11),(4,18),(5,27),(6,38)}  What is the Domain?

• {4,11,5,18}

• {3,11,4,18}

• {3,4,5,6}

• {11,18,27,38}
