Mathematical Writing Challenge
The Challenge: Each Monday, an awkwardly written piece of mathematics will be posted in the box below. Can you re-write it more concisely without changing the mathematical content?
If you let x be zero and you substitute this value into f(x), you find out that there is no way to determine the value of f(0). So we cannot substitute zero for x in this function. But we can substitute any other real number for x and get a number f(x). In fact, by substituting different values for x, we can make f(x) equal any real number we want. From this, we can conclude that the graph of f(x) does not have a highest or lowest point; it goes to both infinities.
