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}
lianna [129]
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}
The answer is A. > because -3 + 7 is -4 and -10 -2 is -12. -4 is greater than -12. good luck!
The values of x and y is x = 2 1/4, y = 6.
We can write the corresponding dimensions:
Larger: smaller
Heigh: 8 : y
Width: 12 : 9
Depth: 3 : x
Since the figures are similar, corresponding values are proportional. This means
y/8 = 9/12
y = 8(9/12)
y = 6
x/3 = 9/12
x = 3(9/12) = 9/4
x = 2 1/4
