Topics rags collectionThere are many ways of writing linear equations, but they usually have constants (like "2" or "c") and must have simple variables(like "x" or "y"). But the variables (like "x" or "y") in Linear Equations do NOThave: 1. Exponents (like the 2 in x2) 2. Square roots, cube roots, etc Ver mais And there is also the General Formof the equation of a straight line: There are other, less common forms as well. Ver mais Sometimes a linear equation is written as a function, with f(x) instead of y: And functions are not always written using f(x): Ver mais Another special type of linear function is the Constant Function ... it is a horizontal line: f(x) = C No matter what value of "x", f(x) is always equal to some constant value.
