• No

If you are looking at a line graph that represents an equation, Where can all of the solutions can be found?

• On the entire graph.

• Above the graphed line.

• Below the graphed line.

Which of the following vocabulary is the same thing as a set of ordered pairs?

• coordinate point

• dependent variable

• independent variable

• output variable.

Identify the format in which a coordinate point is written.

• (x,y)

• (independent variable, dependent variable)

• (domain, range)

• all of the above

Is the following data a function?

(1,2), (2,4), (3,6), (4,8), (5,10)

Choose the best option for the answer.

• Yes; They are a function because all the coordinate points are different.

• No; because all the x-values are different.

• Yes; because the x-values do not repeat.

• No; becasue I see the number appears more than once.

A relation where every input in matches with exactly one output is called what?

• Relation

• Linear

• Exponential

• Function

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.

All of the x values or inputs are called what?

• Domain

• Range

• Relation

• Function
