Scribe post

Hello everyone. Today in class we got our Rational Expressions tests back. Then Mr.K went over a few questions that people had trouble with. Afterwards Mr.K put up some questions on the board to review on function notation are two of the questions that we were given.
B)f(2x)substitute in a 2x to replace the X
Then we had a question where we were asked to graph the points heres one of them:
y=2x; xEbrace0,1,2,3,4,5,6close brace
Mr.K said that it would be easier if we made a table of values even though were not asked too.
0 0
1 1
2 2
3 3
4 4
5 5
6 6
from the table we found the Domain and Range
the Domain is from(-∞,∞) R=(-∞,∞)
We also learned that we can write from negative infinite to positive infinite two different ways
1)(-∞,∞)the we usually write it and
The last thing that we did was vote when our unit test would and it will be this Thursday the last day before the break.
The homework for tonight is Ex.54 the whole thing
And tomorrow's scribe is Kristin
see ya:)
