Answer:

Step-by-step explanation:
<u>Given function is:</u>

Put x = 3
![f(3) =3(3)^2-4(3)+5\\\\f(3)=3(9)-12+5\\\\f(3)=27-12+5\\\\f(3)=15+5\\\\f(3)=20\\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=f%283%29%20%3D3%283%29%5E2-4%283%29%2B5%5C%5C%5C%5Cf%283%29%3D3%289%29-12%2B5%5C%5C%5C%5Cf%283%29%3D27-12%2B5%5C%5C%5C%5Cf%283%29%3D15%2B5%5C%5C%5C%5Cf%283%29%3D20%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)

Answer:
162.24 ft
Step-by-step explanation:
So you first find the area of one side.
5.2 x 5.2 = 27.4
Then you times it by 6, because a cube has 6 sides.
27.4 x 6 = 162.24 ft
Range is the outputs possible
w(r(x))=(2-x^2)-2
w(r(x))=2-x^2-2
w(r(x))=-x^2
therefor the range is from 0 to -∞
