Answer:
y=a(x+4)^2 +1, for a real number a hat is different of 0.
Step-by-step explanation:
If we know only the vertex, there are many quandratic equations.
* Result: Vertex (m,n), the quadratic equation is y= a(x-m)^2 + n for a real number a that is different of 0.
Here, the vertex (-4,1), we have the equation: y=a(x+4)^2 +1, for a real number a hat is different of 0.
Hope you understand.

Answer:
x= 4.24 
y= 4.24
Step-by-step explanation:
1) I began by analyzing the given number, which in this case is the hypotenuse. I know the hypotenuse is equal to x√2. 
2) I divided 6 by √2, which gave me 4.24.
