Find the area lying above the x-axis and under the parabola `y=4x-x^2`

Explanation

To find the area lying above the x-axis and under the parabola given by the equation \( y = 4x - x^2 \), we can follow these steps:

### Step 1: Find the points where the parabola intersects the x-axis
To find the points of intersection with the x-axis, we set \( y = 0 \):

\[ 4x - x^2 = 0 \]
