Question

Which of the following is a logarithmic function?
y=0.25x
y=x^0.25
y=log0.25^x
y=(0.25)^x

Answer 1

A logarithmic function is one that involved the log (logarithmic) function. The only choice that involved using the log function is the third choice: y=log0.25^x

Hope this helps

Answer 2

Answer: Option C     log$.25^{x}$

Explanation:

Logarithmic function is the one which involves log before writing any variable or constant value. We have natural log function also which is denoted as ln.

and it is such kind of function if we consider two variables x and y

then if x increases y will also increase

and it is inverse function of exponential

suppose if we have  y = logx

then in terms of exponent it will become $e^{y} =x$
