Question

Which function is equivalent to f(x) = lnx? f( x) = log 3x f( x) = log bx f( x) = log ex f( x) = log 10x

Answer 1

The equivalent function is

`f(x) = log_(e)x`

Explanation:

We have the function,

f(x) = lnx

Now, the natural logarithm and the common logarithm are related by,

lnx = (logx)/(loge)

But this is not given

So, we assume that the first number after log is the subscript,

hence we don't have log3x but ㏒₃x

And similarly, instead of logex, we have
`log_(e)x`

Hence this is the equivalent function
