A recent study of 50 U. S. chess players details such things as the number of years the players have been active and the chess ratings of the players. (A chess rating is a number from 100 to about 3000, with a higher number indicating greater expertise.) The chess rating data for the sample of 50 players are summarized in the following histogram:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

what is the question?

step-by-step explanation:

it is x equals 3   plese mark me really need it
