Question

Which statement is true?
y = log10X is not a logarithmic function because the base is greater than 0.
y = log 13x is not a logarithmic function because the base is a square root.
y = log, x is not a logarithmic function because the base is equal to 1.
y = loga x is not a logarithmic function because the base is a fraction.
​

Answer 1

Answer:

$y = log_{1}(x)$

is not a logarithmic function because the base is equal to 1.

Step-by-step explanation:

A logarithmic function is of the form

$y = log_{a}b(x)$

where

$a \ne0 \: or \: 1$

Therefore

$y = log_{10}(x)$

$y = log_{ \sqrt{2} }(13x)$

$y = log_{ \frac{1}{2} }(x)$

are all examples of logarithmic functions.

$y = log_{1}(x)$

is not a logarithmic function because the base is equal to 1

Answer 2

Answer: y = log, x is not a logarithmic function because the base is equal to 1.
