Consider the function f(x) = 3^x. Which statement MUST be true?
A) f(3)/f(1) = f(6)/f(4)
B) f(3)·f(1) = f(6)·f(4)
C) f(3) – f(1) = f(6) – f(4)
D) f(3) – f(1) = f(-3) – f(-1)

To analyze the function ( f(x) = 3^x ), let’s evaluate each statement:
A) ( f(3)/f(1) = f(6)/f(4) )
Calculating both sides:
– ( f(3) = 3^3 = 27 )
– ( f(1) = 3^1 = 3 )
– ( f(6) = 3^6 = 729 )
– ( f(4) = 3^4 = 81 )
So, left side ( = frac{27}{3} = 9 ) and right side ( = frac{729}{81} = 9 ). This statement is true.
B) ( f(3) cdot f(1) = f(6) cdot f(4) )
Calculating both sides:
– ( f(3) cdot f(1) = 27 cdot 3 = 81 )
– ( f(6) cdot f(4) = 729 cdot 81 )
Since ( 729 cdot 81 ) is much larger than 81, this statement is not true.
C) ( f(3) – f(1) = f(6) – f(4) )
Calculating both sides:
– Left side: ( 27 – 3 = 24
