From the given set of equation Y = log3x is a logarithmic function.
What is logarithmic function ?
" Logarithmic function is defined as the function which represents the inverse of the exponential function."
Exponential function expressed as
[tex]y = a^{x}[/tex]
According to the question,
Given functions ,
- Y=log3x : In the given log3x is known as logarithmic function of 3x.
So Y is equals to logarithmic function of 3x.
[tex]Y = log_{10} 3x\\\\\implies3x = 10^{y}[/tex]
It's inverse is exponential function
It is a correct answer.
- y-3, y = x, y = x + 3 are linear function with degree equals to one.
Can not be expressed in exponential form.
All these are not logarithmic function.
Hence, Y = log3x is a logarithmic function.
