Tables and Graphs Input Output

Which function table matches the line graphed.

• 
• 
• 

What algebraic equation shows the relationship between the independent and dependent variables?

• y = ax

• y = x + 12

• y = -3x

• y = 

• the independent variable is distance
• the independent variable is d=25 t
• the dependent variable is time
• the dependent variable is distance

• The output is:  s+3
• The output is:  s-1
• The output is:  s-3
• The output is: s ÷ 2 
  

On a graph, which axis shows the INDEPENDENT variable?

• x-axis

• y-axis

• neither

• it changes

On a graph, which axis shows the DEPENDENT variable?

• x-axis

• y-axis

• neither

• it changes

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.
