Question
Consider the following functions for non-zero positive integers, p and q.
f(p, 1) = p
; g(p, 1) = p
Which one of the following options is correct based on the above?
Options :
𝑓(2,2) = 𝑔(2,2)
𝑓(𝑔(2,2), 2) < 𝑓(2, 𝑔(2,2))
𝑔(2,1) ≠ 𝑓(2,1)
𝑓(3,2) > 𝑔(3,2)
Answer :
𝑓(2,2) = 𝑔(2,2)
Solution :
Option 1 :
f(2, 2) = 22 ⇒ 4
g(2, 2) = 22 ⇒ 4
f(2, 2) = g(2, 2) ⇒ True
Option 2 :
f(g(2, 2), 2) = f(4, 2) = 42 ⇒ 16
f(2, g(2, 2)) = f(2, 4) = 24 ⇒ 16
f(g(2, 2), 2) < f(2, g(2, 2)) ⇒ Not True
Option 3 :
g(2, 1) = 21 ⇒ 2
f(2, 1) = 21 ⇒ 2
g(2, 1) ≠ f(2, 1) ⇒ Not True
Option 4 :
f(3, 2) = 32 ⇒ 9
g(3, 2) = 32 ⇒ 9
f(3, 2) > g(3, 2) ⇒ Not True
