Question 995047
The parabolic function is already in standard form, so all that information asked is easy to find.  Intercepts on x you solve for f(x)=0.  Vertex and symmetry axis, you just read from the function definition.  Leading coefficient will be   {{{1}}}, so parabola opens upward.


<pre>
vertex                  (-1,-9)
axis of symmetry         x=-1
roots                   -4  and  +2
y-intercept             evaluate f(0).  y=-8 where x=0,.

You have enough information, or data, to make a sketch of the graph.
