The function f is defined for all positive integers n as \(f(n)= \frac{n}{n+1}\)
Quantity A |
Quantity B |
f(1) × f(2) |
f(2) × f(3) |
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.
QUANTITY Af(1) x f(2) \(=\frac{1}{1+1}\)x\(\frac{2}{2+1}\)
\(=\frac{1}{2}\)x\(\frac{2}{3}\)
\(= \frac{1}{3}\)
QUANTITY Bf(2) x f(3) \(=\frac{2}{2+1}\)x\(\frac{3}{3+1}\)
\(=\frac{2}{3}\)x\(\frac{3}{4}\)
\(= \frac{1}{2}\)
Since \(\frac{1}{2}>\frac{1}{3}\), the correct answer is B
Cheers,
Brent
