Question 1068679: Which equation could generate the curve in the graph below?
mc018-1.jpg
y = –2x2 + 3x – 5
y = –2x2 – 4x – 2
y = –2x2 – 16x– 28
y = –2x2 +16x –28

You can put this solution on YOUR website!
Your link is a local link (or has lost it's host computer information).
You need to have a global link accessible to others.
Check the value of the function when x=0.
That'll narrow down the choices.
I'm assuming it's going to be -28 so it'll be between the last two.
Choose another value, say x=1, calculate the values, match it to the graph, and then you'll know which one it is.
