However, we can integrate functions that have points of discontinuity. Examples… Let’s look at the graph… Find 1 Discontinuity at x = 0!!! –1 1 2 –1 Areas of rectangles: What does our calculator give us on this one???**Discontinuous Integrable Functions**As we already know, a function is not differentiable where it is discontinuous. However, we can integrate functions that have points of discontinuity. Examples… Explain why the given function is not continuous on [0, 3]. What kind of discontinuity occurs? Removable discontinuity at x = 2**Discontinuous Integrable Functions**As we already know, a function is not differentiable where it is discontinuous. However, we can integrate functions that have points of discontinuity. Examples… Use areas to show that The thin strip above x = 2 has zero area, so the area under the curve is the same as A Trapezoid!!!**Discontinuous Integrable Functions**As we already know, a function is not differentiable where it is discontinuous.
