Study Notes
Function Operations
- Multiplication of Functions: This operation combines two functions by multiplying them together, denoted as ( (f \cdot g)(x) = f(x) \cdot g(x) ).
- Division of Functions: This operation involves dividing one function by another, represented as ( (f / g)(x) = f(x) / g(x) ).
- Addition of Functions: This operation combines two functions by adding them together, expressed as ( (f + g)(x) = f(x) + g(x) ).
Parent Function
- Parent Function: Refers to the most basic form of a function, often represented by simple polynomial, trigonometric, or exponential functions, such as (f(x) = x).
Transformations of Specific Functions
- Action of (B) on (F(x) = |x|): The action implies a transformation, typically affecting the graph's symmetry or orientation, possibly involving stretching or compressing the absolute value function.
- Action of (D) on (F(x) = x^3): This action modifies the cubic function, potentially altering its domain or range, which can affect its inflection points and overall shape.
- Action of (C) on (F(x) = \sin(x)): This transformation may adjust the amplitude or period of the sine wave, influencing how many cycles occur over a given interval.
- Action of (A) on (F(x) = e^x): This action typically modifies the exponential growth behavior, potentially shifting the graph up, down, or altering the base of the exponential function.
