Hello, misty.

Answer 41

hi Misty :)

Answer 42

it is "find \(k(3)\) for the function \(k(n)=3n^2\)?

Answer 43

i mean is that the one you are unsure of?

Answer 44

Yes, thats her problem.

Answer 45

ok then \[\large k(3)=3\times 3^2=27\] is correct

Answer 46

27 is not a choice on there

Answer 47

n = 3
So, 3 to the power 2 = 9
3 times 9 = 27...
