The word for the punctuation mark, on the other hand, comes from Îºá¿¶Î»Î¿Î½ (or kÅlon), which means âlimbâ or âclauseâ â and it is used because one of the main functions of the colon is to separate two clauses, where the second clause explains or follows from the first.
The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation.
Note: If the original function is a one-to-one function, the inverse will be a function. Definition: The inverse of a function is the set of ordered pairs obtained by interchanging the first and second elements of each pair in the original function.Should the inverse of function f (x) also be a function, this inverse function is denoted by f -1(x).Note: If the original function is a one-to-one function, the inverse will be a function. [The notation f -1(x) refers to inverse function.se the horizontal line test to determine if a function is a one-to-one function. If ANY horizontal line intersects your original function in ONLY ONE location, your function will be a one-to-one function and its inverse will also be a function.
