A relation is what it sounds like. A relation between numbers and/or objects.

A function is just a special type of relationship. In order for a relation to be a function, it must have only one output for one input.

On a graph, the x-axis is the input and the y-axis is the output. If you draw a vertical line through a point on the x-axis and there is only one point on that vertical line, then it is a function.

The only graph that meets these criteria is the first graph.

Coordinate grid with plotted ordered pairs, point A at negative 5, 4 point B at 4, 7 point C at negative 2, 7 point D at negativ

RideAnS [48]

The answer should be answer A. (A,C,D,K)

You can easily figure this out by just looking at the graph. Just look at all points that are in the blue region(overlapping shaded area) and see all the points inside.

H is not included because it falls on the dotted line. Any point that falls on a dotted line does not satisfy both inequalities.

If the line were solid however, then the point would satisfy both inequalities. This is because the line would include the greater than or equal to symbol "≥" which means that the point could equal to 8 or be less than 8. Since the symbol is not used, it doesn't satisfy both equations.
