Answer:
<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)

Answer:Infinite solution
Step-by-step explanation:
For Inequalities

3y-6x>2
and 
3y-6x<1
The required Inequalities have no solution because they do not share the common region for a common solution
But if signs of both inequalities is changed then the system has infinite number of solution.

3y-6x<2
and 
3y-6x>1
