  1. 1.4 Simplifying Algebra Expressions 9.2.1.1 Understand the definition of a function. Use functional notation and evaluate a function at a given point in its domain.

  2. Guiding Question: How can you represent everyday information into algebraic form? • Lesson Objective: Simplify and Evaluate Algebraic Expressions. • Key Terms: Order of Operations, Like terms, simplify

  3. Guiding Question: How can you represent everyday information into algebraic form? • Order of Operations (PEMDAS) • Parentheses • Exponents • Multiply/Divide (from left to rt.) • Add/ Subtract (from left to rt.)

  4. Guiding Question: How can you represent everyday information into algebraic form? • Like Terms – 2 terms are alike when they have the same variables (letters) raised to the same exponents. • Ex. 7x2y3 + 8x2y3 • Ex. 7x3y2 + 8x2y3

  5. 1. Y2 – 2xy2 – x for x = 2 and y = 3 • 2. (2g – 1)2 – 2g + g2 for g =3 • 3. 4t – 3s2 + s3 for s = -3 and t = -2 • 4. 3a2b - ab3 + 5 for a = 5, b=2 Guiding Question: How can you represent everyday information into algebraic form? BE CAREFUL WITH THE SIGNS WHEN SUBSTITUTING NUMBERS IN FOR VARIABLES.

  6. Guiding Question: How can you represent everyday information into algebraic form? • Assignment: Glue Factory Worksheet
