Study Notes
- A polynomial function is a function in the form p(x) = a_nx^n + a_n-1x^(n-1) + ... + a_1*x + a_0, where n is the degree and a_n is the leading term and leading coefficient.
- In polynomial functions, the exponent of the leading term is the degree.
- Quadratic polynomial functions have the highest exponent of 2.
- The term without a variable is the constant term.
- To identify the degree and leading coefficient of a polynomial function, find the leading term (highest degree term) and determine the coefficient of that term.
- In the video, the speaker provides examples of identifying the degree, leading term, and leading coefficient of different polynomial functions.
- The video also covers expanding polynomial functions using the FOIL method and converting them to standard form.
- The examples in the video include polynomial functions with real coefficients, negative exponents, and variable terms in the denominator.
- The speaker emphasizes that polynomial functions do not include radical signs, fractions with variable denominators, or negative exponents with variables as bases.
- The video covers how to determine if a given function is a polynomial function based on the restrictions on the function's form.
- The speaker provides several examples of identifying the leading term, leading coefficient, and degree of different polynomial functions, including factoring and expanding using the FOIL method.
