The total revenue in Rupees received from the sale of x units of a product is given by `R(x)=13 x^2+26 x+15`. Find the marginal revenue when`x = 7`.

Explanation

To find the marginal revenue when \( x = 7 \) for the given total revenue function \( R(x) = 13x^2 + 26x + 15 \), we will follow these steps:

### Step 1: Differentiate the Revenue Function
The marginal revenue \( MR \) is defined as the derivative of the total revenue function \( R(x) \) with respect to \( x \).

Given:
\[
R(x) = 13x^2 + 26x + 15
