Watch "How Wolves Changed Rivers" on YouTebe This video got nothing wrong if you search it and you see wrong things you have the right to report me but fr I need help

***And answer the following question please ASAP ASAP please

1. Why did the "deer" (they are really elk) leave the valleys when the wolves were re-introduced to Yellowstone?

2. When the elk left the valleys, what happened to the vegetation? Give specific examples.

3. Once the vegetation changed, what wildlife came back?

4. How did the wolves change the rivers?

5. How did the elk change the rivers when the wolves were removed from Yellowstone National Park?

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

can you make your screen more see able?

then i might be able to .
