Find the range of values of x such that the quadratic function f(x)=(x+5)^2-16 is positive.

f(x)=(x−5)2−16

Set the polynomial equal to y

to find the properties of the parabola.

y=(x−5)2−16

Use the vertex form, y=a(x−h)2+k

, to determine the values of a, h, and k

.

a=1

h=5

k=−16

Since the value of a

is positive, the parabola opens up.

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

answer: it is d
