1. Today we will revisit graphing inequalities . The we
will discuss graphing and lines . Read Chapter 1.2
carefully. Review your notes about graphing inequalities.
a) Practice: Page 21 #1—-19 odd, 39, 41.
b) Practice: Page 23 #49–63 odd, 67, 71, 77.
c) Practice: Page 24 #87, 89.

Short as signment : To review inequalities.
1. Simply find the critical values for each of these
expressions :
2. Solve the fol lowing inequalities using a number line as
we did in class. Also ex press your answer in
interval notation (e.g., (a, b]).

1. De termine whether these functions are symmetric about
the origin, about the y-axis, or neither.
2. Use the distance formula to find the distance between
the following pairs of points. Leave your answer
in the form of a square root . Do not approximate.
a) (2, 4), (7, 6)
b) (4,−2), (−6, 3)
