### Polynomial Functions

In mathematics, a polynomial function is a function that can be expressed in terms of a polynomial. Here are some examples of polynomial functions, represented with their equations:

1. **Function \( g(x) \):**
   \[
   g(x) = x^3 + x^2 - 8x - 12
   \]
   This is a cubic polynomial function because the highest exponent of \( x \) is 3.

2. **Function \( f(x) \):**
   \[
   f(x) = x^2 + 4x + 3
   \]
   This is a quadratic polynomial function because the highest exponent of \( x \) is 2.

3. **Function \( h(x) \):**
   \[
   h(x) = x^2 + 3
   \]
   This is another example of a quadratic polynomial function.

4. **Function \( s(x) \):**
   \[
   s(x) = x^2 - 3x
   \]
   This is also a quadratic polynomial function.

Each of these polynomial functions can be graphed on a coordinate plane. The shape of the graph will depend on the degree of the polynomial and the coefficients in the equation. 

#### Graphical Interpretation (Not Provided in Image)

- A cubic function (\( g(x) \)) will have a graph that can change direction up to two times and has the potential to have three real or complex roots.
- A quadratic function (\( f(x) \), \( h(x) \), and \( s(x) \)) will have a parabolic shape, opening upward if the coefficient of \( x^2 \) is positive and downward if it is negative.

Understanding these functions and their graphs is key in algebra and calculus for solving equations and inequalities.
