Question 1146276
--------------------------------------------------------------------
quadratic function if vertex is (-3,-3) and y intercept is (0,6)
--------------------------------------------------------------------


{{{y=a(x-(-3))^2-3}}}
{{{y=a(x+3)^2-3}}}
{{{y+3=a(x+3)^2}}}

{{{a=(y+3)/(x+3)^2}}}
substitute given point:
{{{a=(6+3)/(0+3)^2}}}

{{{a=9/9}}}

{{{a=1}}}

-

{{{highlight(y=(x+3)^2-3)}}}-------------you could multiply and simplify if you want to.
