Chapter 4 - Quadratic Functions - 4.2 Graphing Quadratics in Vertex Form - 4.2 Exercises - Page 317: 16

a) $(5,6)$ b) $x= 5$ c) negative d) $h= 5$ and $k= 6$ e) $(3,2)$

All values are read directly from the graph. a) The vertex is $(5,6)$. b)The equation of the axis of symmetry is $x= 5$. c) The parabola opens downward, and so, the value of $a$ is negative. d) $h= 5$ and $k= 6$. e) The point symmetric point to the point $(7,2)$ is $(3,2)$.
