Understanding Function Graphs
A graph of a function visually represents the relationship between its input (x-values) and output (y-values). It helps in understanding the function's behavior, such as its shape, intercepts, and turning points.
Common Function Types:
- Linear Functions: y = mx + b (straight line)
- Quadratic Functions: y = ax² + bx + c (parabola)
- Trigonometric Functions: sin(x), cos(x), tan(x) (periodic waves)
- Exponential Functions: y = ax (rapid growth/decay)
Graphing Examples
| Function | Description |
|---|---|
| y = x | A straight line passing through the origin with a slope of 1. |
| y = x^2 | A parabola opening upwards, with its vertex at the origin. |
| y = sin(x) | A periodic wave oscillating between -1 and 1. |
| y = 2^x | An exponential growth curve. |
