# Which of the following is a logarithmic function?

Students were enquired to answer a question at schools and to claim what is most important for them to succeed. Out of the many replies, the one that that stood out was practice. Successful people generally are not born successful; they become successful thru hard work and perseverance. This is how you can complete your goals. These are some question and answer examples that you will possibly use to develop your knowledge and gain insight that will guide you to keep up your school studies.

## Question:

Which of the following is a logarithmic function?

Option 3 is correct.

Step-by-step explanation:

Option 1: y = 0.25x

since, power of x is 1 in this function.

Thus this is a linear function.

Option 2: y =

Here, in this function power of x is 0.25

So, It is a polynomial function.

Option 3: y =

In this function we can see the term with log written.

Thus this is a Logarithmic function with base 0.25

Option 4: y =

In this function x is in the power of 0.25.

Thus this is a exponential function.

They would possibly hopefully help the student take care of the question by make use of the questions and answer examples. You can easily then have a discussion with your classmate and continue the school learning by studying the question to one another.
