Show that the function given by `f(x) = 7x-3`is strictly increasing on R.

Explanation

To show that the function \( f(x) = 7x - 3 \) is strictly increasing on \( \mathbb{R} \), we will follow these steps:

### Step 1: Find the derivative of the function
The first step is to differentiate the function \( f(x) \).

\[ f(x) = 7x - 3 \]
