Question

# The function is

- Strictly increasing
- Strictly decreasing
- Neither increasing nor decreasing
- None of these

Hint:

### We are given a function. We have to find if it's increasing or decreasing. A function is increasing when it's first order derivative is positive. A function is decreasing when it's first order derivative is negative. We will find the first order derivative of the given function to find the answer.

## The correct answer is: Strictly increasing

### The given function is f(x) =

We will take the first-order derivative of the function.

The quantity x^{2} is always positive.

And all other values are positive constants.

So, the total value of the first-order derivative is positive.

It means f'(x) > 0

It means the given function is strictly increasing.

For such questions, we should check the rules of increasing and decreasing function.
