Question 89295: The problem reads:
Match the graph with its equation.

A) y = –x^2 – 1
B) y = –x^2 + x
C) y = –x^2 + 1
D) y = –x^2 + 2x
The graph has a downward parabola and the axis looks like it is at 0, 0.5. Can you please provide an explanation showing all the steps? Thank you.

Vertex: ( -b/(2a), f(x) )
A) y = –x^2 – 1
Vertex: ( 0, -1 )
B) y = –x^2 + x
Vertex: ( 1/2, 1/4 )
C) y = –x^2 + 1
Vertex: ( 0, 1 )
D) y = –x^2 + 2x
Vertex: ( 1, 1 )
