Alright, so function f of x is 1200 times 1 .055 to the power of x.
00:06
That should be to the power of x, not times x.
00:10
Since we're talking about, we're supposed to be an exponential function.
00:14
Okay? i'm assuming that's to the power of x, okay? because we're talking about investments, and that's an exponential function like this.
00:21
Okay, how does the average rate of change between 21 and 25 years compared to the average rate of change between 1 and 5 years? all right, this phrase average rate of change is really weird to me.
00:34
What that means you're basically asking for like, like how to what's up with this? like this number is different.
00:41
Like this is per year, but when you're doing them with like an average between five years, like this is between five years, it's also between five years that changes a little bit.
00:49
So the way i interpret this is that i did the one in five one first.
00:54
Okay, so you make x1, you get 1266.
00:57
You make x5, you get 1 ,568 .3...
