Characteristics of Quadratic Functions: Determine zeros, axis of symmetry, max/min value, and vertex from given parabolas.
Graphs of three quadratic functions on a coordinate plane, each showing a parabola with labeled axes. The first parabola opens downward with a vertex at (-2, 4), the second opens upward with a vertex at (1, -1), and the third opens upward with a vertex at (-1, -3). Each graph includes a grid for reference.
