Answer:

Axis of Symmetry ⇨ x = -1

Explanation:

⟺ From
y=a(x-h)^2+k

Our axis of symmetry equals the value of h.

In easier way, we can look at the graph and notice that the minimum point/vertex is at (-1,-9)

We use the value of h to answer.

Thus, the axis of symmetry is x = -1.

Formulas:

Here is some formulas that might benefit you in Quadratic Function.

$h=-(b)/(2a)\\k=(4ac-b^2)/(4a)$

h = Axis of Symmetry (transformation of the graph with x-axis)

k = basically the transformation of the graph with y-axis.
