What are the coordinates of the vertex of the graph? is it a maximum or minimum?

Vertex ( 0,1) and it is maximum.

Step-by-step explanation:

Given  : graph of parabola .

To find : What are the coordinates of the vertex of the graph? Is it a maximum or minimum.

Solution : We have given the graph of parabola

Vertex : the highest point ; the top.

Vertex : ( 0 , 1) because it cut at y ,

When the parabola opens down, the vertex is the highest point on the graph is called the maximum, or max.

Therefore, Vertex ( 0,1) and it is maximum.

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.
