Question 1181396
-------------------------------------------------------
axis of symmetry is x=-1 the vertex is on the x axis
-------------------------------------------------------


Symmetry axis is a vertical line, and the y component of vertex is 0.


{{{highlight_green(y=a(x+1)^2+0)}}}



------------------------------------------
parabola passes through the point (1,-4).
------------------------------------------


Solve this for "a".
{{{-4=a(1+1)^2}}}
