Gr8 Math STAAR Review

Is this mapping a function or not a function? 

• Function
• Not a Function 

Which graph does NOT pass the vertical line test?

• Graph 1
• Graph 2
• Graph 3
• Graph 4

• It is a function because no vertical lines hit it twice.
• It's not a function because a vertical line hits it twice.
• It's not a function because no vertical lines hit it twice.
• It is a function because a vertical line hits it twice.

• It is a function because no vertical lines hit it twice.
• It's not a function because a vertical line hits it twice.
• It's not a function because no vertical lines hit it twice.
• It is a function because a vertical line hits it twice.

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.

Find the rate of change

• 1
• 2
• 11
• Not a constant slope/Non-Linear

Does this relation represent a function?
(1,5), (1,6), (1,7), (1,8), (1,9)

• Yes
• No

Is the graph proportional or non proportional?

• Proportional because it is a straight line and passes through the origin (0,0).
• Non-Proportional because it doesn't pass through the origin (0,0).

Why does this graph show a non-proportional relationship?

• It doesn't, it is proportional because it is a straight line
• It goes through the origin
• It does not go through the origin
• It is a straight line

A gymnast burns 15 calories a minute.

• Proportional
• Nonproportional
