Consider the curve $y = - x^{2} + 4$ . Below is shown the graph of a piecewise function $f$ made up by a horizontal line segment and part of the parabola $y = - x^{2} + 4$ . The area under the graph of $f$ and above the $x -$ axis has been shaded. Write down an expression for the area under the graph of $f$ and above the $x -axis for x > 0$ .
