Rewrite the given quadratic function in standard form and identify the values of a, b, and c. Calculate the axis of symmetry using the formula x= − 2 b/2a and solve for the coordinates of vertex using the axis of symmetry. Determine if the vertex is a minimum or maximum and state why

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.

50-38=12
