Find the range for the function k(n) = 2n2 when D = {–2, 1, 3}. R = {2, 8, 18} R = {2, 18, 36} R = {4, 12, 27} R = {4, 12, 16}

K(n) = 2n^2.....where domain (n) = -2
k(-2) = 2(-2^2) = 2(4) = 8
k(n) = 2n^2.....where n = 1
k(1) = 2(1^2) = 2(1) = 2
k(n) = 2n^2...where n = 3
k(3) = 2(3^2) = 2(9) = 18
so ur range k(n) = { 2,8,18}
Answer:
![k = -0.1733](https://tex.z-dn.net/?f=k%20%3D%20-0.1733)
Step-by-step explanation:
The first step to solve this equation is placing everything with the exponential to one side of the equality, and everything without the exponential to the other side. So
![24e^{4k} = 12](https://tex.z-dn.net/?f=24e%5E%7B4k%7D%20%3D%2012)
![e^{4k} = \frac{12}{24}](https://tex.z-dn.net/?f=e%5E%7B4k%7D%20%3D%20%5Cfrac%7B12%7D%7B24%7D)
The ln is the interse operation to the exponential, so we apply the ln to both sides of the equality.
![\ln{e^{4k}} = \ln{\frac{12}{24}}](https://tex.z-dn.net/?f=%5Cln%7Be%5E%7B4k%7D%7D%20%3D%20%5Cln%7B%5Cfrac%7B12%7D%7B24%7D%7D)
![4k = -0.6931](https://tex.z-dn.net/?f=4k%20%3D%20-0.6931)
![k = -\frac{0.6931}{4}](https://tex.z-dn.net/?f=k%20%3D%20-%5Cfrac%7B0.6931%7D%7B4%7D)
![k = -0.1733](https://tex.z-dn.net/?f=k%20%3D%20-0.1733)

Knowing the faces alone does not uniquely identify polyhedrons.
For example with 5 faces you could have a square pyramid, but also a triangular prism.
