Answer 1

Parabola is the is the graph of f(x) = –(x + 3)(x + 1). In the mathematics field, the parabola is one of the plane curves that are mirror-symmetrical. It is also approximately U-shaped.

Parabola fits lots of superficially various mathematical descriptions that are proved to define precisely the similar curves.

The parabola description involves a line and a point.

Answer 2

Answer:

Refer the attached graph below.

Step-by-step explanation:

Given : Function - $f(x) = -(x + 3)(x + 1)$

To find : The graph of the given function.

Solution :

We plot the graph of the given function.

The given function is the graph of a parabola which is in U shaped.

In the given parabola function (-2,1) is the vertex of the parabola.

(-2,0) is the focus of the parabola.

The points of parabola touches the x-axis are (-3,0) and (-1,0).
