Question 1091036
------------------------------------
 f(x) = –2(x - 3)^2 + 6, 
-----------------------------------


Opens downward, and vertex is a maximum point.  The factor {{{-2}}} tells this.  Factor is negative.


Two zeros.  Vertex being at (3,6) and ABOVE the x-axis,  and parabola opening DOWNWARD makes the graph cross the x-axis in two places.




{{{graph(300,300,-8,8,-8,8,-2(x-3)^2+6)}}}
