Identifying Functions and Linear Functions

This question refers back to last chapter, but it is a good question. Recall that a set of ordered pairs represents a relation, but not all relations are functions. Is this 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.

Identify whether the graph represents a function. Explain. If the graph does represent a function, is the function linear? 

• No, because for every domain value there is not exactly one range value
• Yes; because for every domain value there is exactly one range value. Yes it is linear.
• Yes, because for every domain value there is exactly one range value. No; it is not linear.

Is this a function or not a function? If so, is the function linear?

• Function; not linear
• Not a Function
• Function; linear

Identify whether the graph represents a function. Explain. If the graph does represent a function, is the function linear?

• Yes, because every domain value is paired with exactly one range value. No; it is not linear.
• Yes, because every domain value is paired with exactly one range value. Yes; it is linear.
• No, because every domain value there is not paired with exactly one range value

Is this function linear or non linear?

• Linear
• Non Linear

Is this table a function or not a function? If it is a function, does it represent a linear function?

• Function; linear function
• Not a Function, therefore not a linear function
• Not a function, but it is a linear function. 
• Function, but not a linear function.
