Chris has a large collection of hockey cards and wants to get of rid of some of his hockey cards. He gives 2 cards away on day 1
WINSTONCH [101]
<span>We define

day--------------------------X
hockey cards away ------------f(X)
</span><span>He gives 2 cards away ----------------on day 1----------f(X)=2   X=1
</span>He gives 4 cards away ----------------on day 2----------f(X)=4   X=2
He gives 8 cards away ----------------on day 3----------f(X)=8   X=3
the sequence of cards away      2,4,8,16,32,64,128,256,512,1024 

f(x) = 2**(x)

The answers are

D 
<span>Each day corresponds to a unique amount of hockey cards in this sequence.</span> 
And B <span>The graph of this sequence would pass the vertical line test.

Each element of the Domain (X = day), relates to a single value of f(x) = number of hockey cards

That is, every value of X must have only one corresponding value of f(x)
(One value of y, for each input X)

This can also be checked by using the vertical line test. 

If we plot f(x) and we draw vertical lines in the curve, we can verify that at every input the line intersects only one point of f(x)</span>

This isn't to diffuclt. So, to the formula for the area of a circle is 2\pi r, or instead of r, you can put D, which is r times 2

The diameteris 2.5, so, the answer would be

pi times 2.5, where pie = 3.14

So, the answer is 2.5 * 3.14 = 7.85 or 7.9
