Study Notes
Graphing Calculator Functions
- To input data into a table, use Stat Edit.
- For finding linear regression, navigate to Stat Calculate 4.
- Accessing matrices involves pressing 2nd Matrix A to view matrix A.
- To enter or edit a matrix, use 2nd Matrix Edit.
Graph Behavior
- The expression x^2 indicates that the graph opens upward.
- The expression -x^2 indicates that the graph opens downward.
Function Analysis
- When provided with a function, it is effective to plug in the equation and utilize both a graph and table for problem-solving.
- To derive an equation using regression, input the given table and apply linear regression.
Key Algebra Concepts
- The Quadratic Formula is expressed as:
- *x = (-b±√(b²-4ac))/(2a)**.
- Completing the square involves adding a specific term to a quadratic expression to convert it into a perfect square trinomial.
- Factoring refers to rewriting an expression as the product of its factors.
Imaginary Numbers
- The value of i² is equal to -1.
Working with Systems of Equations
- In a system of equations, it is advisable to change all variables to a common variable for simplification before solving.
Matrix Creation
- To create a matrix, organize each equation horizontally and align each variable in vertical columns.
