If the zeros of a quadratic function are 3 and 8, what are the factors of the function?
o a. (x+8) and (x - 3)
ob. (x - 8) and (x+3)
o c. (x+8) and (x + 3)
d. (x-8) and (x - 3)

Option D

If the zeros of a quadratic function are 3 and 8 then the factors of function are x - 8 and x - 3

Solution:

Given that zeros of quadratic functions are 3 and 8.

Need to determine the factors of quadratic function

Lets function be f(x) that is variable is x.

Zeros of quadratic functions are 3 and 4 means,

x = 3, x = 8 are solutions of f(x)

When x =3 ,( x – 3 )  = 0

When x = 8 , ( x – 8 ) = 0  

Hence we can say that ( x – 3 )  and ( x – 8 ) are factors of polynomial f(x).hence correct option is D that ( x – 3 )  and ( x – 8 )

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
