Answer:
vertex = (3, 6 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = 2(x - 3)² + 6 ← is in vertex form
with vertex = (h, k ) = (3, 6 )
Ratio is just a fraction in other form. To create ratio we can just make fraction and transform it into ratio, so

Now we can simplify the ratio/fraction

= 4:3 - its the result
