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 .

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
