Answer:
The vertex is the point (-5,-6)
Step-by-step explanation:
we know that
The equation of a vertical parabola written in vertex form is given by the expression
[tex]f(x)=a(x-h)^2+k[/tex]
where
a is the leading coefficient
(h,k) is the vertex
we have
[tex]f(x)=9(x+5)^2-6[/tex]
so
The leading coefficient is a=9
The vertex is the point (-5,-6)
