Question

Help please

Answer 1

5 and 8

Answer 2

Are you sure, I really need a positive answer and an explanation or guidance on how the answer is found

Answer 3

So to find out the easy way, you do the "vertical line test" in which if you draw a vertical line, it will only intersect at one point on the graph.

Answer 4

Oh okay so 5 and 8 would be your positive answers?

Answer 5

While answer 8 may look like it will intersect, there is never a point ion which the line goes straight down.
