• (0, 3)

• (0, -3)

• (-1.5, 0)

• (3, 0)

Function or not a function?

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

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

Is this a function?

• yes

• no

What does the y-intercept mean?

• 100 degrees at the start of the day

• 0 degrees at the start of the day

• 115 degrees is where it crosses the y-axis

• 110 degrees is where it's exactly on the line

The graph represents the height of a burning candle.  What is the meaning of the y-intercept?

• the time it takes to burn the entire candle
• the rate at which the candle is losing height
• the change in the height of the candle each hour
