Answer:
Step-by-step explanation:
a = 1 because if is not written what x^2 multiply, it means that x^2 multiply 1
b = 6 b is the term that multiply x
c = 6 c is the therm without x
axis of symetry = -6/2 = -3
the x of vertex is same of the axis of the symmetry so it is -3
if we subistute x with this value we can find the y of vertex
(-3)^2 + 6(-3) + 6 = 9 -18 + 6 = -3
Vertex (-3, -3)
