What is the vertex of the graph of  y  = –x2

Vertex : ( 0, 0).

Step-by-step explanation:

Given  : y = –x².

To find: What is the vertex of the graph.

Solution : We have given parabolic equation :  y = –x².

Vertex form of parabola: y = ( x -h)² + k.

Where, ( h ,k )  are vertex.

On comparing y = –x² with  y = ( x -h)² + k.

h= 0 , k= 0.

Vertex : ( 0, 0)

Therefore, Vertex : ( 0, 0),

the least common denominator is 40
