Study Notes
Linear Functions
- Linear equations graph as straight lines.
- The highest exponent in a linear function is 1.
Quadratic Functions
- Quadratic functions include a variable with an exponent of 2.
- Graphs of quadratic equations form a parabola, which can open upward or downward.
Exponential Functions
- Exponential functions have variables in their exponents.
Cubic and Higher Degree Functions
- Cubic functions contain variables raised to the power of 3.
- 4th degree functions involve variables raised to the power of 4.
Absolute Value
- Absolute value represents the distance from zero, disregarding negative signs.
Function Naming
- The name of a function is based on the highest exponent present.
Characteristics of Lines
- Horizontal lines maintain a constant Y value.
- The slope of a horizontal line is 0; vertical lines have an undefined slope.
Asymptotes
- Asymptotes are lines that approach a curve without ever touching it.
Irrational Numbers
- Irrational numbers have non-repeating, non-terminating decimal expansions, e.g., Euler's number (E=2.71828...).
Function Notation
- f(3) indicates substituting X with 3 to find the corresponding Y value.
- The equation Y = f(X) shows the relationship between input (X) and output (Y).
Parent Graphs
- Parent graphs represent the simplest form of functions.
- Examples include linear parent graph (Y = X) and quadratic parent graph (Y = X²).
Algebra Operations
- Dividing by a fraction equals multiplying by its reciprocal.
- An exponent of 0 results in a value of 1.
Vertex of a Parabola
- The vertex is the highest or lowest point of a parabola.
Finding Intersection Points
- To determine intersections between a line and a parabola, use a graphing calculator's intersect function.
Classifying Lines and Parabolas
- Lines are categorized as positive slope, negative slope, 0 slope, or undefined slope.
- Parabolas fall into two categories: open upward or open downward.
Perfect Squares
- A number is a perfect square if its square root is a positive integer.
