(2, 1), (4, 3). (6, 5), (8,7)

(1,  2), (3,  4), (5, 6), (8, 7)

Step-by-step explanation:As we can observe from the answers the representation is about the pair of points. We can sort it out by excluding the wrong options.

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

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
