The 1st choice would be TRUE - if we draw vertical lines down the graph, we can see that there are no points which touch the line more than once.
The 2nd choice would be FALSE - by looking at the graph, we can see that there is indeed x values which are less than 2
The 3rd choice would be TRUE - looking at the y values on the graph, there is no y value below 2
The 4th choice would be FALSE - intervals are points where the graph stops and begins to form another graph from that point (there may be a better definition of this than mine), and from the plot given, there is only one interval
The 5th choice would be FALSE - the straight line would definitely be a linear function, but the parabola is not, as it involves a curve
So your answers should be options 1 and 3
Hope this helped!
