Chapter 4 - Quadratic Functions - 4.2 Graphing Quadratics in Vertex Form - 4.2 Exercises - Page 317: 17

a) $(2,10)$ b) $x= 2$ c) negative d) $h= 2$ and $k= 10$ e) $(5,-6)$

All values are read directly from the graph. a) The vertex is $(2,10)$. b) The equation of the axis of symmetry is $x= 2$. c) The parabola opens downward, and so, the value of $a$ is negative. d) $h= 2$ and $k= 10$. e) The point symmetric point to the point $(-1,-6)$ is $(5,-6)$.
