Read the following material of an exploring Calc 1 class to complete the questions 18-20.  Some weird functions and its analysis We are familiar with a lot of elementary functions, such as power functions, exponential functions, logarithmic functions, trigonometric functions and so on. They are differentiable, continuous on their domain. However, there are so many functions which have some discontinuities. In fact, a continuous function is not always differentiable either, such as . is a cusp on the graph. As the limit of rate of change, the right limit and the left limit are sometimes not equal, which causes the derivative to not exist. It’s sad. But luckily, at least we have definitions to go by. After all, when some disputes arise, the best way is to return to the DEFINITION. Weird functions don’t necessarily have weird behavior everywhere, it’s just not obvious to figure it out. Consider the function below
