### Scribe

In yesterday's class Mr. K put us into groups and we compare linear functions and exponential functions. As a group we found out that this two functions has a lot of common, one of it is that when you substitute 0 to both of its equation you would get its y-intercept. Like in a linear function , if you put 0 on x, y=ax+b you would get b which is the y-intercept. Also, in an exponential function when you put 0 in its x you would also get the y-intercept of the function, y=a.b^x. Also, we talked about its differences and one of them is that a linear function has a constant slope while an exponential function has a common ratio. Then we talked about exponential decay, which we found out that if the multiplication factor is 0 < b < 1 its an exponential decay because the number is decreasing very fast at that number but it won't get into 0 eventually.

Also, in yesterday's class we talked about compound interest and Euler's number. Euler's number "e" is like any kind of number like pi its a little bit lower than 3 and its value is 2.718281828459....and its non repeating. To learn a little bit more of Euler's number you could check this site.

Well, that's yesterday's class and we didnt really cover a lot of stuff because there was Bus ridership and that consume our learning time. Well thats all folks!

The next scribe is CJ....
