There are four types of linear graphs. • converse is true: any linear function f : Rn → Rm can be written as f(x) = Ax for some A ∈ Rm×n • representation via matrix multiplication is unique: for any linear function f there is only one matrix A for which f(x) = Ax for all x • y = Ax is a concrete representation of a generic linear function Linear functions and examples 2–4. -The Role of b in the equation y = mx + b Let us look more closely at the above linear function, y = 3x - 1, and its graph, shown above. A) Find the domain of the function. Linear functions can always be written in the form f (x) =b +mx or f (x) =mx +b; they’re equivalent where b is the initial or starting value of the function (when input, x = 0), and m is the constant rate of change of the function.
