Question

What logarithmic function represents the data in the table?

Answer 1

x f(x)
25 2
125 32
625 4

Answer 2

well looking at x in terms of powers of 5 you get

\[25 = 5^2.... 125 = 5^3 ...and.... 625 = 5^4\]

and the powers seem to be the f(x) values....

so I'd say its a base 5 log

Answer 3

f(x) = logx 5

f(x) = log5 x

f(x) = 5 log x

f(x) = log 5x

Answer 4

b or d ?

Answer 5

nope its base 5

so

\[\log_{5}(25) = 2\]

so

\[f(x) = \log_{5} x\]

Answer 6

so b
