So if a is z, so it's z plus 2 times z minus 2.

It's a z.

1, 1, z, z looks like this z would look like, z would look like that.

That choice B, the argument of z z 1 is equal to the argument of z z 2. Now lets think about this a little bit.

Let me make the z in a different color. f of z.

Z squared minus 4 is z plus 2 times z minus 2.

So that's z plus 2, a plus b, times z minus 2, a minus b.

(t time z 2 minus z 1). Is this equal to the argument of (z 2 minus z 1)?

If the MER valuation index Y or Z (predetermined numbers to be decided by the Committee), meaning extreme overvaluation or extreme undervaluation of exchange rate

The United Nations publishes a Human Development Index (HDI) every year, which consists of the Life Expectancy Index, Education index, and Income index.

I have a minus 8, but we want a z plus 2 and z minus 2.

It's z plus 2 times z minus 2.

In part A, we figured out... we figured out that z minus z1 is equal to T times Z two minus Z one

So, it's going to be a scaled down version of Z 2 minus Z 1.

If the MER valuation index Y or Z (predetermined numbers to be decided by the Committee), meaning that there exist economic reasons to explain growth in PCGNI

So times z plus 1, times z plus 1.

So it's z plus 4 times z minus 2.

And, let's draw the vectored Z 2 minus Z 1 so let's say that this here is the vector and lets draw the vector Z 2 minus Z 1 now what would T times Z 2 minus Z 1 look like?

(t 1) times (z 2 minus z 1) is going to look like this. This is (t minus 1) times (z 2 minus z 1).

This is (t times z 2 minus z 1) and the green one, just to be clear is (z 2 minus z 1) is that.

So what is z sub one times z sub two?

And let's see, this z cancels out with this z.

So this is equal to 7z times z plus 1, times z plus 2, times z minus 6.

This right here would be T times Z 2 minus Z 1. Now what would T minus 1 times Z 2 minus Z 1 look like?

Times z squared minus 4 all of that over z to the third plus 2z squared plus z equals.

8 divided by 4 is 2 times so we can definitely factor out a z here, so we get z times z squared plus 2z plus 1.

I wrote a z minus b here.

We could factor out a z squared.

He's got a Z on his chest.

Or in this case, z plus 2 times z minus 2.

All of that over 4 times z plus 2, times z.

So it's z squared plus 4 times z squared minus 4.

This is equal to the limit and I've change colors arbitrarily as z approaches 2 of z plus 4 over z squared plus 4 times z plus 2.

A search index does not yet exist. Do you want to create the index now?

You put in a z, you are going to get out a negative 2 times whatever that z is plus 3.
