The rule of a function in math is what relates the input value to the output value. For example, if f(x) = x2, the "function rule" is to square the input value to get the output value.
f(x) = ...f is the name of the function, and x is the variable. I guess you could say x is the root of the function, because it is what the function relies on.
It is true that a rational function is a function whose equation contains a rational expression. This is used in various math classes.
if a function has a unique y value for each x value the function is one to one.
Normally you don't need such advanced math in the kitchen.
string art includes geometry which is a type of math
The string function is strlength and it is evoked to return the length of a string.
Without any function is impossible. So I'll assume you mean any coded function, in which case the predefined function below is your answer.$string = strrev($string);
The angles and the geometric shapes that the string makes is in relation to geometry.
string length is a function use to check the lenght of a string i.e number of alphabets in a word or sentence.
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.
between parentheses: funname ("string")
