- Polynomial Equations: Polynomial equations are equations in which the highest power of the variable is 3 or more.
Types of Functions
There are several types of functions, including:
- Linear Functions: Linear functions are functions in which the output is directly proportional to the input.
- Quadratic Functions: Quadratic functions are functions in which the output is proportional to the square of the input.
- Polynomial Functions: Polynomial functions are functions in which the output is proportional to the input raised to a power of 3 or more.
Graphing Equations and Functions
Graphing equations and functions is an essential skill in algebra. Graphs provide a visual representation of the relationship between the input and output of a function, making it easier to understand and analyze the behavior of the function.
Types of Graphs
There are several types of graphs, including:
- Linear Graphs: Linear graphs are graphs in which the output is directly proportional to the input.
- Quadratic Graphs: Quadratic graphs are graphs in which the output is proportional to the square of the input.
- Polynomial Graphs: Polynomial graphs are graphs in which the output is proportional to the input raised to a power of 3 or more.
