C4Q1 Functions & Describing Graphs

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.

Does the graph represent 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
• Yes, because the points are discrete

• No, because the points are not continuous

CCSS.HSF.IF.C.7

Is this a function?  Why or why not? 

• Yes, because none of the domain numbers repeated.
• Yes, because none of the range letters repeated.
• No, because 3 goes to A and 4 goes to A.
• No, because A gets used twice.
