The graph that represents a function is the last graft on the screen (pic shown below)
2×-2=-4
-4 × -2 = 8
8 × -2 =-16
-16×-2 =32
32 ×-2 = -64.
therefore the answer is -2.
The 1:3 ratio means that the distance from A to the point is 1/4 of the distance from A to B.
The difference of y-coordinates is 10-8 = 2. 1/4 of that is 2·1/4 = 1/2, so the point of interest will have y-coordinate 8 + 1/2 = 8 1/2. This apparently corresponds to the first selection:
... (6 1/2, 8 1/2)
.026 because 2.6%*100 is 0.026
76 divided by 4 is 19. Add a zero and the answer is 190.
Hope this helps you !!
