Answer:
Cube
Step-by-step explanation:
The cubed root of 8 = 2 because 2³ = 8.
So 8 is perfect cube.
In economics and investments, opportunity cost is the amount of money that a company could have gained, but lost because they took another course of action. This is especially applicable to situations wherein a company decides on which of the two events they would choose.
In other words, opportunity cost can be the net gain or loss that a company obtains when upon getting to the decision. Suppose, we chose a spending of 4.5%, the opportunity cost would be:
Opportunity cost = <span>$7 trillion (4.5% - 4.1%)
Opportunity cost = $7 trillion(0.004)
Opportunity cost = $0.028 trillion or $28 billion
Therefore, the opportunity cost is $28 billion.</span>
Ok so you are correct that x is input and y is output
the
you could be talking about a function in general or a kind of function normally used called a one-to-one function which I will assume you are talikning about
one-to-one funciton has that for every input, there is only 1 output, ie, x never repeats with a diffent y
example
(1,2), (2,2) is a function since x didn't repeat
(1,2), (1,3) is not since x repeats with a different y
points given are
(-5,1),(-3,-2), (3,0),(1,1),(2,0),(6,4)(8,-2),(8,7)
we see that the points (8,-2) and (8,7) make it not a function since it is the same input (8) that gives 2 different outputs
professor octavious is wrong since 8 repeats
