Make the given changes in the indicated examples of this section and then solve the resulting problems. In Example $4,$ change $2 t-7$ to $7-2 t$ and then solve.

Okay. What we want to do is we actually want to determine some exponential model that will represent this data right here. And so we know an exponential model is given by y equal to a times some base value raised two X. In this case or excess T. So why is equal to A. Times and based value raised to T. Okay, so we need to find out what A. Is and what our bases basically. So let's go ahead. Um And let's focus on, you know that where it crosses the Y axis and that is at 0 1200. And so we know that when tier zero then why is 1200? So 1200 is equal to A. Times B raised to the zero and remember anything raised to the zero is one. And so that means this constant is actually 1200. So now we have why is equal to 1200 times Face times time. Okay, so now what we want to do is to go ahead and come up with um somehow the base. So what do we know? We know that the base raised to T. Is equal to y. Divided by 1200. And so that means that the base is going to be. Why over 1200 raised to the one over T. Power. Okay. So if I do this and I say ok so when and we're gonna start here at one right to equal to one. So we would have 720 over 1200 raised to the first power is equal to be which is equal to about 0.6 year old which is 3/5 right? And so if I get the same ratio every single time then that means my basis is 0.6 or 3/5. So now if I do this one if I do 4 32 I do yeah. 4 32. Over 1200. And that is the square root we get 0.60 which is equal to my base. And so we're just gonna keep doing it and make sure that it holds true for every single one of them. So then the third one would be that we have 259 0.20 over 1200 raised to the one third. Oh that should equal B. So if I do we get 0.6 and let's verify the last one. So the last one should be 155.5 to over 1200 to the 1/4. Okay. And that is sure enough 0.60 Which is three faith. So my exponential model is why is equal to 1200 times 3/5 raised to the T.
