Answer 1

Answer: Choice B

{(0,0), (1,2), (2,4), (3,4)}

===============================================

Explanation:

A function is only possible if each x input leads to exactly one y output. For choice A, we have x = 1 lead to y = 3 and y = 5 at the same time, which is what the points (1,3) and (1,5) are saying. Therefore, choice A is not a function.

Choice C is also ruled out because x = 2 repeats itself as well. In this case, (2,3) and (2,4) means that the input x = 2 leads to the two outputs y = 3 and y = 4.

Choice D can be eliminated also for two reasons: x = 0 shows up twice, so does x = 2.

Only choice B has each x value listed one time only. So that means each input leads to exactly one output.

If you graph choice A, C or D, you'll find they fail the vertical line test. The vertical line test is where you test if you can draw a vertical line through more than one point on the graph. If you can draw a vertical line through more than one point on the graph, then the relation fails to be a function.

Answer 2

B. A fraction is when the X don’t have some of the same numbers down it’s row
