Module 2: Lesson 2.01 - Quadratic Functions

Polynomial Function (written definition) : a continuous function that can be described by a polynomial equation in one variable

What are the rules for a polynomial Function of x with degree n? : n is a nonnegative integeran, a_n-1....a_2, a_1, a_0 are real numbers != 0

What is the degree of the linear function: f(x) = ax + b? : One

What are polynomials with a degree of 2 called? : Quadratic Functions

When does a parabola open upward/downward? : If leading coeff is positive: upwardIf leading coeff is neg: downward

Vertex Form of a Quadratic Function : f(x) = a(x - h)^2 + k

What can all quadratics be solved by? : Quadratic Formula

Quadratic Formula : x = -b ± √(b² - 4ac)/2a
