Question

Please explain why A(x) < 0 for all x in the interval shown?

Answer 1

Part D, why is it true? Is it not positive in [R, S] ?

Answer 2

yes it is positive in [R, S]

Answer 3

but A(x) represents the area between `0` and `x`

Answer 4

So does it mean, when adding all the areas within the shown graph that it is overall negative?

Answer 5

since the positive area is so small, the overall area between [0, S] would still be negative

Answer 6

okay. Thanks!
