- A cubic parent function is a function that represents a curve with an S-shaped pattern.
- It is defined by the equation y = ax^3 + bx^2 + cx + d, where a, b, c, and d are constants.
- The degree of the polynomial determines the number of bends in the curve. A cubic function has two bends, which contribute to its distinctive shape.

### Absolute Value Parent Function

- An absolute value parent function is a function that represents a V-shaped graph.
- It is defined by the equation y = |x|, where |x| denotes the absolute value of x.
- The graph of this function is symmetric with respect to the y-axis.

### Square Root Parent Function

- A square root parent function is a function that represents the principal square root of a number.
- It is defined by the equation y = √x, where √x denotes the square root of x.
- The graph of this function is a curve that starts at the origin (0,0) and extends to the right.
