math
A formula or graph are two ways to describe a math function. How a math function is described depends on the domain of the function or the complexity of the function.
it shows the function of things
It is an increasing odd function.
sign function is math matrix function
GetA is a math function and not a string function.
math
A linear function is increasing if it has a positive slope. To find this easily, put the function into the form y=mx+b. If m is positive, the function is increasing. If m is negative, it is decreasing.
