Chapter 4 - Quadratic Functions - 4.2 Graphing Quadratics in Vertex Form - 4.2 Exercises - Page 317: 18

a) $(-2,2)$ b) $x= -2$ c) positive d) $h= -2$ and $k= 2$ e) $(-5.5,16)$

All values are read directly from the graph. a) The vertex is $(-2,2)$. b)The equation of the axis of symmetry is $x= -2$. c) The parabola opens upward, and so, the value of $a$ is positive. d) $h= -2$ and $k= 2$. e) The point symmetric point to the point $(1.5,16)$ is $(-5.5,16)$.
