Turning points- where the graph of a function changes from increasing to decreasing or vice versa

Local maximum point – highest point or “peak” in an interval
function values at these points are called local maxima

Local minimum point – lowest point or “valley” in an interval
function values at these points are called local minima

Extrema – plural of extremum, includes all local maxima and local minima

Day 3: Review and Homework

NOTE: Test Friday



Chapter 5 part 2:

5.5 Roots of Real Numbers
Vocab
  • square root
  • nth root
  • principal root
5.6 Radical Expressions
Vocab
  • rationalizing the denominator
  • like radical expressions
  • conjugates
RECALL:

Steps to simplify a square root.
  1. Factor the radicand into as many squares as possible.
  2. Use the product property to isolate the perfect squares.
  3. Simplify each radical
To eliminate radicals from a denominator or fractions from a radicand, you can use a process called rationalizing the denominator. To rationalize a denominator, multiply the numerator and denominator by a quantity so that the radicand has an exact root.

Getting Started: Assignment1

It’s not too early to begin thinking about your success in Algebra 2 this summer! Since many of you have spent the past year in geometry class, it will be a good idea to refresh your algebra skills. Below are the prerequisite skills from algebra 1 along with some practice problems. This assignment will not be checked or graded. However, there will be a test on these skills the first or second day we return to school.

If you have trouble with any of these problems, solutions will be posted by Sunday.
(Feel free to email me or leave a comment if you have questions.)


Before you begin Algebra 2, you should be able to:

I. Solving Equations and Inequalities (ch 1 in text book)
  • Solve any one variable equation
  • Solve absolute value equation
  • Solve Inequalities
  • Solving Compound and Absolute Value Inequalities
II. Linear Relations and Functions (ch 2 in text book)
  • Identify a function, domain and range
  • Use function notation to evaluate a function
  • Find slope of a line given two points or a graph.
  • Write the equation of a line given slope and y-intercept, slope and a point, two points, or a graph.
  • Graph any line: Including vertical & horizontal, linear inequalities and absolute inequalities
II. Systems of Equation (ch 3 in text book)
  • Solve Systems of Equations by Graphing
  • Solve Systems of Equations Algebraically (substitution and Elimination)

Practice Problems( When downloading choose PDF or HTML)

Extra Help: Before class and after class.

Words from Ms. Garcia:

Come to class everyday with notebook, and something to write with and a good attitude.

Keep in mind students that our summer course is usually taught in a year. That being the case, we must move fast and smile everyday. If you have questions, please ask!! If not, we will move right past you.

Good Luck
