Study Notes
Algebra II Unit 2 Key Concepts
- A linear equation equates two linear expressions or a linear expression and a constant.
- A linear inequality expresses that two linear expressions or a linear expression and a constant are not equal.
- A system consists of two or more linear equations or inequalities considered together, allowing for simultaneous solutions.
- The standard form of a linear equation is expressed as Ax + By = C, where not both A and B can equal zero.
- Linear functions exhibiting a nonzero slope guarantee the existence of an inverse function, which is a critical property in function analysis.
- Gaussian elimination is a method used to solve systems of equations or inequalities by adding or subtracting multiples of equations to eliminate variables, facilitating easier solution derivation.
- Composing a function with its inverse function yields x, confirming that they undo each other's effects within their respective domains.
- A piecewise function is characterized by different definitions over distinct intervals of its domain, allowing flexibility in function behavior.
