Functions of Two Variables. If x1, x2, x3, …, xn are real numbers, then (x1, x2, x3, …, xn) is called an n -tuple. This is an extension of ordered pairs and triples. A function of n variables is a function whose domain is some set of n -tuples and whose range is some set of real numbers.
26 Ιουν 2024 · The following are some examples of linear equations: 2x − 3y = 6, 3x = 4y − 7, y = 2x − 5, 2y = 3, and x − 2 = 0. A line is completely determined by two points. Therefore, to graph a linear equation we need to find the coordinates of two points.
