1000 is better you get 1 staple for every $3 as opposed to 1 staple every $2.50
You get double for $0.50 more per staple
The fourth set of ordered pairs is the function.
The definition of a function is that no matter what x value you put in, you get only one y value out. So no x value will have more than one answer. However, in the first 3 choices, you can see that each one has an x value that has two different y value answers.
In grouping 1, x = -1 gives us both y = 1 and y = -1.
In grouping 2, x = 0 gives us both y = 1/2 and y = 3/4.
And in grouping 3, x = -2 gives us both y = 1 and y = 2.
Therefore, the last grouping is your function.
All you do is multiply 300*.27=
81
Interest = Principle(Rate)(Time)
$84.50 = P(0.0325)(4)
$84.50 = P(0.13)
$84.50/0.13 = P
P = 650
$650 was originally deposited.


Or 2 times 2 times 2 times 2 times 2 times 2 times 2

So, 2^6 is:
64
Now, 7^4 is:
2,401
Hope it helps!
