<h3>
Vertex Form</h3>
Step-by-step explanation:
Vertex form of quadratic function with vertex (h, k) is y=a(x-h)²+k,
So y= (x - 2)² - 9 is vertex form with vertex (2, -9)
X= 8sqrt(2)
sorry i don’t know how to type the radical, but where the “sqrt” is the would be the symbol
I’ve included the work below
