Functions Review for REMOTE Learning Lesson 3/24

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values

• No, because it DOES NOT pass the vertical line test. There are two points on the same vertical line.

Is this graph a function and how can you tell?

• Yes its a function cause it doesn't cross itself

• No it's not a function because it goes through the origin

• No it's not a function because it does not pass the vertical line test. The x value 4 has two different outputs (y values) of -2 & 2

• No it's not a function because it is not a straight line.

Is this table a function and how can you tell?

• Yes its a function because no x value repeats

• No it's not a function because the y value 4 repeated

• Yes, it isn't a function because the x value 2 is repeated

• No it's not a function because the x value 5 repeats and has two different y values of 10 & 12

Which graph does NOT pass the vertical line test?

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

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.

Is this a function? Explain.

• Yes; it passes the horizontal line test.
• No; it is not a straight line.
• Yes; it passes the vertical line test.
• No; there is a line connecting the dots.
