Study Notes
Functions
- Functions are a fundamental concept in calculus
- Functions describe relationships between variables
- Functions can be represented by equations, graphs, tables, or verbal descriptions
Functions: Domain and Range
- Domain: The set of all possible input values (x-values) for a function
- Range: The set of all possible output values (y-values) for a function
- The output of a function depends on the input
- Functions assign a unique output value to each input value
Graphs of Functions
- The graph of a function is a visual representation of the relationship between inputs and outputs
- Points on the graph are ordered pairs (x, f(x))
- The y-coordinate (f(x)) represents the height of the graph above or below the x-axis
- The graph of a function passes the vertical line test; no vertical line intersects the graph at more than one point
Piecewise-defined Functions
- Functions defined by different formulas for different parts of their domain
- Different formulas are applied based on the input value's position in the domain
- Example: absolute value function
Even and Odd Functions
- Even function: f(-x) = f(x) (symmetric about the y-axis)
- Odd function: f(-x) = -f(x)(symmetric about the origin)
Common Functions
- Linear Functions: f(x) = mx + b (straight lines)
- Power Functions: f(x) = x^a (various shapes based on the exponent a)
- Polynomials: Functions formed by sums of terms involving powers of x
- Rational Functions: Functions formed by quotients of polynomials
- Trigonometric Functions: Functions based on trigonometric relationships (sine, cosine, etc)
- Exponential Functions: Functions involving exponential expressions
- Logarithmic Functions: Functions that are inverses of exponential functions
