Agraph of a quadratic function is shown on the grid.

which coordinates best represent the vertex of the graph?
a) (2.4, 0)
b) (0, -1)
c) (-0.4, 0)
d) (1, -2)

D) (1,-2)

Step-by-step explanation:

The vertex for a quadratic function is either the minimum point or the maximum point of the curve depending on the nature of the curve from which the curve changes direction.

In the graph shown for the quadratic function, it has minimum point as the graph opens upwards. So, the vertex is the minimum point of the curve.

The vertex of the graph is .

d? maybe

step-by-step explanation:

y=mx+b
