Lesson 1: graphing quadratic functions
words to know
Quadratic Functions: in the form of ax^2 + bx + c
Nonlinear Functions: graphs of functions that are not in a straight line
Standard Form: a quadratic formula written in ax^2 + bx + c
Parabola: the shape of a graph if a quadratic function
Axis of Symmetry: the line in which parabolas are symmetric
Vertex: the point at which the axis of symmetry meets the parabola
Minimum: the lowest point on a graph, when a > 0
Maximum: the highest point on a graph, when a < 0
