Nettet2 dager siden · The linear function is popular in economics. It is attractive because it is simple and easy to handle mathematically. It has many important applications. Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one … NettetLinear Function. A linear function is a function whose graph is a line. Linear functions can be written in the slope-intercept form of a line. f(x) = mx + b. where b is the initial or starting value of the function (when input, x = 0 ), and m is the constant rate of change, or slope of the function. The y -intercept is at (0, b). NettetHere we show the function of independent random variable is still independent. Share. Cite. Follow edited May 9, 2024 at 19:21. answered Nov 24, 2014 at 3:21.

If one or more vectors from a given sequence of vectors is the zero vector then the vector are necessarily linearly dependent (and consequently, they are not linearly independent). To see why, suppose that is an index (i.e. an element of ) such that Then let (alternatively, letting be equal any other non-zero scalar will also work) and then let all other scalars be (explicitly, this means that for any index other than (i.e. for ), let so that consequently ).
