Question

Consider the function f(x)=3x which statement must be true

Answer 1

A) f(3)/f(1)=f(6)/f(4)

Explanation:

Answer 2

Answer: f(3) − f(1) = f(6) − f(4)

Explanation:

The given function is f(x)=3x

f(3)=3(3)=9

f(1)=3(1)=3

f(3)-f(1)=9-3=6

Also,

f(6)=3(6)=18

f(4)=3(4)=12

f(6)-f(4)=18-12=6

Therefore the correct choice is

C) f(3) − f(1) = f(6) − f(4)
