Answer:
1. not function
2. not function
3. function
4. not function
5. function
Step-by-step explanation:
I was able to determine whether the graphs were function or not by simply using the vertical line test, which tests if the graph has only one output for each input value. In short, if you draw a vertical line in the Cartesian plane, it must intersect the given graph just once for it to be considered a function.
For instance, when you put a vertical line across the curved parabolic graph in no.1, you'll notice that it intersects with two points in the graph. This implies that the graph is not a function.
