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}

The correct option is 1.

Step-by-step explanation:

The given function is

Domain is the set of input values and range is the set of output values.

It is given that the domain of the function is D = {–2, 1, 3}.

Substitute n=-2 in the given function.

Substitute n=1 in the given function.

Substitute n=3 in the given function.

The set of output values is {8, 2, 18}. So, the range of the function is

R = {2, 8, 18}

Therefore the correct option is 1.

step-by-step explanation:

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
