  1. 老师!能不能帮我算一下空气???

    他的状态一定只有固体,液体和气体而以吗?真的吗?
    在空气(大气)中还有其他生物吗?还是只有细菌而已?没有其他根微小的生物了吗?
    我们吸进生体里的空气中有没有营养??
    我们的眼睛真的 看 不到到空气吗?

  2. teacher,pg140,141 what the examples mean ??? *[making first factor negative or 0 ,
    and 2nd , positive or 0 )

    how to know tat max and min value is tat??

    i dunno the 2 example !!!!

  3. Example 9 is to find max. or/and min. values of the expression. After you obtaining this inequality (7y-5)(y+1) 7y-5<=0
    then y must be =0 …. and so on.

    I prefer you use the method i given to u in class.

    Similarly, for example 10.
