A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.
From the graph, we can say that f(a) < f(b) and f(c) < f(d)
Adding both the inequalities;
f(a) + f(c) < f(b) + f(d)
Col. A: f(b) - f(c)
Col. B: f(a) - f(d)
Adding f(c) and f(d) to both sides;
Col. A: f(b) + f(d)
Col. B: f(a) + f(c)
Hence, option A

Can be solved visually by just looking at how far apart on the y-axis the values of f(x) are at points a,b,c,d.
f(b) - f(c) : These two points are pretty far apart, implying that the magnitude of this expression is bigger.
f(a) - f(d) : These two points are not as far apart, implying that the magnitude of this expression is relatively smaller.
Hence, A.
f(b) - f(c) : These two points are pretty far apart, implying that the magnitude of this expression is bigger.
f(a) - f(d) : These two points are not as far apart, implying that the magnitude of this expression is relatively smaller.
Hence, A.
