Answer:
C. Domain: {}, Range: all real numbers;No, it is not a function
Step-by-step explanation:
From the diagram in the attachment, the domain is {}.
The reason is that, the furthest the graph could extend is 8 to the right and left of the y-axis.
The range of the relation is all real numbers. The reason is that, the graph extends up above and below the x-axis without bounds.
The relation is not a function, because its graph failed the vertical line test.
See graph
The correct answer is C.
Check the picture below.
now, looking at the picture's scaling, from the lower-left-corner up to 20 is 5 squares, the rectangles you see in the picture are 40 units each, namely 10 squares. Every square is 4 units, it goes up 12 squares, namely 48 units, and goes to the right by 30 squares plus 4 more, 34 squares, that's 136 units.
well, if we were to make a triangle for the slope, check the picture, it'd look like that.
Why is the slope negative? well, because is going down from left to right.
