Answer:
The vertex of the parabola is (-2,0)
Step-by-step explanation:
The given function is:
Now, in order to find the vertex for the parabola, that is v(h,k), comparing the above equation with the standard form of equation that is , we get
a=-3, b=-6 and c=0
We know, and
, therefore
and
Thus, the vertex is given as:(h,k)=(-2,0).
