Question

What is the logarithmic function modeled by the following table?

x f(x)
4 1
16 2
64 3
f(x) = log4x

f(x) = logx4

f(x) = 4 log10x

f(x) = x log104

Answer 1

The answer is A. f(x) = log4x

Answer 2

Answer: option 1.


`log_(4) x`

x f(x)

4 log (4) 4 = 1 ... because 4^1 = 4

16 log(4) 16 = 2 .... because 4^2 = 16

64 log (4) 64 = 3 .... because 4^3 = 64
