Plug in the point (1,6) into each answer choice.
A) f(n) = 5n - 1
f(1) = 5(1) - 1 = 5 - 1 = 4
(1,4) ≠ (1,6)
Answer choice A is incorrect.
B) f(n) = 5n + 1
f(1) = 5(1) + 1 = 5 + 1 = 6
(1,6) = (1,6)
Answer choice B is correct.
C) f(n) = 4n + 3
f(1) = 4(1) + 3 = 4 + 3 = 7
(1,7) ≠ (1,6)
Answer choice C is incorrect.
D) f(n) = 4n - 3
f(1) = 4(1) - 3 = 4 - 3 = 1
(1,1) ≠ (1,6)
Answer choice D is incorrect.
Your answer is B) f(n) = 5n + 1
