The answer is f(2y) = 8y^2 - 8
In order to find this, we need to put 2y in where x was in the original equation. From there, we follow the order of operations to simplify.
f(x) = 2x^2 - 8
f(2y) = 2(2y)^2 - 8
f(2y) = 2(4y^2) - 8
f(2y) = 8y^2 - 8
-7/24, because you can just do this question in reverse to figure out an answer. (3/8 - 2/3)
Set? Are you missing part of the question
Answer:6
If you were to multiply 6*6*6 you would get 216
