Answer:
Step-by-step explanation:
Given that the graph of a parabola.
We need to determine the function that represents the graph.
<u>Function of the graph:</u>
From the graph, it is obvious, that the x - intercepts of the graph are 
Thus, the equation can be written as

Simplifying the terms, we have;

Multiplying, we get;

Adding the like terms, we have;

Writing it as function, we have;

Hence, the function of the graph is

Answer:
Tangent line states that a line in the plane of a circle that intersect the circle in exactly one point.
Common external tangent states that a common tangent that does not intersects the line segment joining the centers of circle.
Common internal tangent states that a common tangent that intersects the line segment joining the centers of circle.
Circumscribe polygon states that a polygon with all sides tangent to a circle contained within the polygon.
Therefore:
A polygon with all sides tangent to a circle contained within the polygon = Circumscribe polygon
A common tangent that intersects the line segment joining the centers of circle = Common internal tangent
A common tangent that does not intersects the line segment joining the centers of circle = Common external tangent
a line in the plane of a circle that intersect the circle in exactly one point = Tangent line
