#### Answer:

Domain :

Range :

#### Explanation:

Let y = a polynomial of degree n

As

Here, n = 2 and

y = -x^2-14x-52)=-(x+7)^2-3<=-3, giving

The domain is

See graph. graph{(-x^2-14x-52-y)(y+3)((x+7)^2+(y+3)^2-.01)=0 [-20, 0, -10, 0]}

Graph shows the parabola and its highest point, the vertex V(-7, -3)
