This graph represents a function.

a. true
b. false

( with photo )

To see if a graph is a function you must do the vertical line test. This test is passed when a vertical (up and down) line is placed anywhere on the graph and the graph only crosses the line once. This graph does not pass the vertical line test, and therefore is not a function.

Hope this helped! Let me know if there is anything I need to clarify or explain more in depth!

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
