Examples of parent functions include linear functions, quadratic functions, cubic functions, and exponential functions. Each of these functions has a unique graph and set of properties that define their behavior.

Common Parent Functions

1. Linear Function: The linear function is represented by the equation y = x. It is a straight line with a slope of 1 and a y-intercept at the origin.

2. Quadratic Function: The quadratic function is represented by the equation y = x^2. It is a parabola that opens upwards and has its vertex at the origin.

3. Cubic Function: The cubic function is represented by the equation y = x^3. It is a curve that passes through the origin and has a point of inflection at the origin.

4. Exponential Function: The exponential function is represented by the equation y = e^x. It is a curve that grows rapidly as x increases and approaches zero as x decreases.

Transformations of Parent Functions

Transformations of parent functions involve shifting, stretching, and reflecting the graph of the function. These transformations can be applied to any parent function and can significantly alter the appearance and behavior of the graph. The most common transformations include:
