 The absolute value of a number is its distance away from zero. ◦ Absolute values are always non-negative ◦ |x| = x if x≥0 ◦ |x| = -x if x<0  Evaluating absolute value expressions 1.Substitute values in first 2.Simplify inside the absolute value 3.Take the absolute value 4.Simplify further, if needed

 Read Section P.1 (pages 2-11)  Page 11 #1, 3, 9-29 ODD, Every Other Odd (EOO)  Read Section P.2 (pages 13-20)

 Name, period, due date in the upper right corner of each page - blue or black ink  Assignment written on the top line of each page – blue or black ink  Each problem numbered and the original problem rewritten - blue or black ink ◦ Word problems may be summarized.  The problem must be worked out in pencil. Sufficient work must be shown.  Skip a line before each new problem.

 In Exercises 1-4, list all numbers from the given set that are: a) Natural numbers b) Whole numbers c) Integers d) Rational Numbers e) Irrational Numbers

 Write the solution graphed below in both interval notation and set-builder notation.

 Clear everything off of your desk except pencils and erasers.

 Use a #2 pencil  Write the teacher name (Mr. Szwast) and Class (Pre-Calculus) at the top  Write and bubble in your name.  Mr. Szwast will collect the bubble sheets in order – do not pass them forward

 Do NOT write in the test booklet – use scratch paper.  Bubble in each answer with a #2 pencil  You will have 45 minutes  No calculator allowed
