No real roots.

x^2 + 2x + 7 = 0

The discriminant = b^2 - 4ac

Help with this question, please!
jonny [76]

Answer:

The last choice is the one you want.

Step-by-step explanation:

Simply take the x coordinate and subtract 4, then do the same with the y coordinate since the vector movement is <-4, -4>.  The first coordinate F is <4,0>.  Subtract 4 from both of those coordinates and end up at <0, -4>.  The second coordinate G is <1, 3>.  Subtract 4 from both of those and end up at <-3, -1>.  The third coordinate H is <2, 6>.  Subtract 4 from both of those and end up at <-2, 2>.  The last coordinate I is <4, 2>.  Subtract 4 from both of those and end up at <0, -2>.
