A)The quantity in Column A is greater.

C)The two quantities are equal.

\(g={(-4,2), (-1,3), (2,-3)}\)
Quantity A |
Quantity B |
\( f(g(-1))\) |
\(g(f(-1))\) |
A)The quantity in Column A is greater.
B)The quantity in Column B is greater.
C)The two quantities are equal.
D)The relationship cannot be determined from the information given.
Col. A: \( f(g(-1))\)
Col. B: \( g(f(-1))\)
We have been given \(g\) at x = -1 is 3 and \(f\) at x = -1 is 2
So,
Col. A: \(f(3)\)
Col. B: \(g(2)\)
Also, \(f\) at x = 3 is -4 and \(g\) at x = 2 is -3
So,
Col. A: -4
Col. B: -3
Hence, option B
