Show that the function `f(x)=2x+3` is strictly increasing function on `Rdot`

Explanation

To show that the function \( f(x) = 2x + 3 \) is a strictly increasing function on \( \mathbb{R} \), we can follow these steps:

### Step 1: Find the derivative of the function
To determine whether the function is increasing or decreasing, we first need to compute its derivative. The derivative of a function gives us the rate of change of the function with respect to \( x \).

\[ f'(x) = \frac{d}{dx}(2x + 3) \]
