Study Notes

Maximum and Minimum Values

The maximum value of the sine function, f(x) = sin(x), is 1.
A function can have a specific minimum value based on its transformations and inherent characteristics.

Function Identification

The function graphed below corresponds to f(x) = cos(x).
When identifying functions from their graphs, key points and symmetry help determine their nature.

Transformations of Sine Functions

For the function f(x) = -2sin(x) + 3, transformations include:
- Reflection across the x-axis
- Vertical stretching by a factor of 2
- Vertical translation upward by 3 units

Properties of Functions

A function described by certain properties must have characteristics such as domain, amplitude, x-intercepts, and y-intercepts.
For example, y = -4sin(x) has a domain of all real numbers, an amplitude of 4, and passes through specific points.

Domain of Cosine Function

The domain of the cosine function, f(x) = cos(x), includes all real numbers, indicating it is defined for every x value.

Amplitude

The amplitude of a sine or cosine graph reflects the distance from its midline to its maximum or minimum value; for the specified function, the amplitude is 2.
