I think a) would be the answer. I proceeded by elimination: the domaine of the function goes from 3 and continues to infinity, so that leaves with a) and b) as possible answers. Both have the same range and both of their functions reflect over the x axis, so we have to compare the two answer by looking at the position of the function in the graph. The function is in the first quadrant (top right corner), so the position of the function has to be at our right, which leads us to a).
A Because if you do 156 x 20 it equals 3120. It’s A because the volume formula is Length x Width x height, And 156 and 20 were the only numbers given.
I think it’s b hope it helps
