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}
I don’t know because it wouldn’t pop up
1. If you're looking for a one-dimensional answer, then the answer would be a triangle (if you're looking at the surface of the cut). The three sides would be the diameter and the slant heights.
2. Again, if you're looking for a one-dimensional answer, the answer would be a rectangle. The four sides would be the diagonals and the heights.
Hope this helps and sorry I couldn't reply sooner!
