Study Notes
Polynomial Function
- A polynomial function is defined as a function that contains no negative exponents.
- These functions are characterized by being continuous over their domain.
Extrema
- Extrema represent the highest and lowest points found on a graph.
- They are crucial for understanding the overall shape and behavior of the polynomial function.
End Behavior
- End behavior describes the direction in which the polynomial function approaches as values of x become extremely positive or negative.
- It provides insights into the function’s limits at both ends of the graph.
x-Intercepts
- The x-intercepts of a function are the points where the function intersects the x-axis, meaning y = 0 at these locations.
- Also referred to as roots or zeros, these points are essential for finding solutions to polynomial equations.
Leading Coefficient
- The leading coefficient is the coefficient attached to the term with the highest exponent in a polynomial.
- It plays a vital role in determining the polynomial's end behavior and overall shape.
Degree
- The degree of a polynomial is the highest exponent present in the function.
- It indicates the highest power of the variable, influencing the number of potential x-intercepts and extrema.
Standard Form
- A polynomial is expressed in standard form when its terms are arranged in descending order based on their exponents.
- This format enhances clarity and allows easier analysis of the polynomial's properties.
