How many diagonals can be drawn from a vertex of an n-gon?

Answer In a poligon of n sides can be drawn n-3 diagonals from each vertex.

Explanation The triangle is the first closed polygon, which has three sides and it is not possible to draw any diagonal from a vertex. In a polygon with four sides it is already possible to draw a diagonal from each vertex to the opposite one. Then diagonals = n-3.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

where are the graphs?
