Siyavula's open mathematics grade 10 textbook, chapter 6 on functions covering linear functions. Is a linear function if the rate of change of the function is constant ie, for every unit that we move in the x direction, the rise in the y direction is constant example.
Linear functions a linear function is a function whose graph is a straight line such a function can be used to describe variables that change at a constant rate. A linear function is a mathematical expression which, when graphed, will form a straight line a linear function is a simple function usually composed of constants . Assignment 1 linear functions by venessa brown the goal of this assignment is to explore the sum, product, quotient and composition of two linear functions. Linear function (plural linear functions) (mathematics) any function whose value on the sum of two elements is the sum of the values of the function on the two.
Understanding linear functions is key to students developing a sound foundation for algebra the common linear function rule y = mx + c presents students with. Determining whether your equation is a linear or non-linear function can be achieved many ways first off, are you looking at a graph of the function, or is it an.
