6.5 liters per 100 km travelled. 30% of 5 is 1.5, so adding this to the original amount results in 6.5
To find the vertex use -b/2a (for the x value which is also the axis of symmetry)
So 2/-2 = -1 Therefore the axis of symmetry is x=-1 Plug in for the y value:
y= -(-1)^2 -2(-1) + 1 y=-1 + 2 + 1 y=2 Vertex (-1,2)
1 is the answer to nthis/...
