Answer:
B. Non-linear; function
Explanation:
The function shown is y =
. A linear graph would be a straight line. Therefore, this graph is non-linear.
To determine if a graph is a function, you would use the vertical line test. That means that if you were to draw a vertical line through the graph, it would only hit one point, no matter where you drew the line. For this graph to not be a function, this vertical line would have to hit more than one point. As it doesn't, that means that this is a function.
