Study Notes
Polynomials Class 9 Notes
- A polynomial is derived from the words 'poly' meaning 'many' and 'nomial' meaning 'term'.
- A polynomial expression consists of variables (indeterminates) and coefficients.
- Coefficients involve the operations of subtraction, addition, non-negative integer exponents of variables, and multiplication.
- Algebraic expressions and polynomials are made up of variables and constants, including arithmetic operations.
- The main difference between algebraic expressions and polynomials is that algebraic expressions contain irrational numbers in the powers.
Algebra 1 Unit 1: Functions, Graphs, and Features
- Students are introduced to the main features of functions through basic graphical modeling of contextual situations.
- Function notation is used to analyze and express features of functions represented in graphs and contextually.
- Tools used to describe contextual situations include:
- Domain and range
- Rates of change
- Intercepts
- Where a function is changing
Algebra 1 Unit 2: Statistics
- Students analyze contextual situations, focusing on single-variable data and then bivariate data.
- The concept of using data to make predictions and judgments about a situation is introduced.
- Univariate data is described through:
- Shape
- Center
- Spread
- Mathematical calculations to support the description
