Answer:

Please let me know if your quadratic is y=-2(x+2)^2+2.

And if so your vertex is (-2,2) and your y-intercept is (0,-6)

Step-by-step explanation:

It says vertex so I'm thinking you meant y=-2(x+2)^2+2.  Please correct me if I'm wrong.

The vertex form of a quadratic is y=a(x-h)^2+k.  It is called that because it tells you the vertex (h,k).

So if you compare the two forms you should see -h=2 while k=2.

-h=2 implies h=-2.

So the vertex is (h,k)=(-2,2).

To find the y-intercept, set x=0 and find y.

y=-2(0+2)^2+2

y=-2(2)^2+2

y=-2(4)+2

y=-8+2

y=-6

So the y-intercept is (0,-6).

The travels you have described are:

                                       (Middle floor) + 8 + 5 - 9 + 7 - 32

                                   =  (middle floor)  + 20 - 41

                                   =  (middle floor)  -  21  brought her to floor #1.

So                                   Middle floor  -  21  =  1

Add 21 to each side:    Middle floor  =  22 

The building has (2 x middle floor)  =  44 floors.
