(-3,0), (0,-4), (2,0), (2,5). This is not a function of X. But what's the best explanation for why out of these choices.
a
(-3, 0) has a negative x-value.
b
(2, 0) and (2, 5) have the same x-value but different y-values.
c
(0, -4) has a negative y-value.
d
(-3, 0) and (2, 0) have the same y-value but different x-values.

B

Step-by-step explanation:

Let's eliminate our options

A: The answer is not A because functions can have negative x values.

B: This one immediately seems right to me because a function cannot have one input that spits out two outputs. This would fail the vertical line test

C: Like A, having negative values in either the x position or y position does not rule out a function. e.g. y = x - 4

D: Unlike B, having two of the same y coordinates does not rule out a function. The function could be quadratic. e.g. y = (x+3)(x-2)

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent
