Question

this is a graph with a parabola on it? http://img692.imageshack.us/img692/6728/121013160103.png

Answer 1

It's definitely not the first two, since a negative A Coefficient makes the parabola point down

Answer 2

It's also not the fourth one since that graph has a vertex at (1, -4). So the only equation that would work is the third one. y=x^2+2x-3

Answer 3

thanks

Determine whether the graph of y = −2x2 − 3x + 10 opens up or down and whether it has a maximum or minimum point.

Down and Maximum

Down and Minimum

Up and Maximum

Up and Minimum

Answer 4

That graph would open down and it has a max.
