Approximationg area under a curve f(r) using geometry 1. Find the total area of the shaded region, which was formed by shading from the graph of the piecewise function f(x) towards the x-axis on the interval [0,10). 2. Now, consider that any region beneath the r-axis has negative area (while any region above the a axis has positive area). This defines net area. Find the net area of the shaded region above. 3. Using basic geometric shapes, how can you make an approximation of the net area beneath the function f(x) = 212 - 2x graphed below on the interval [0,5]? 4. Can we always easily use some simple geometric shapes to make a good approximation of net area? Draw a function and its shaded region which would be more challenging to approximate using basic geometric shapes
