As with most misconceptions, the longer these misconceptions are held, the harder it is for students to “unlearn” them. Early experiences with functions can help prevent the two particular misconceptions listed below.
Constant functions are not functions. A function is called constant if all inputs are assigned the same output. In other words, as the inputs vary, the outputs ...
