Nettet13. nov. 2024 · Definition: Linear Function. A linear function is a function of the form f(x) = mx + b. The graph of a linear function is a line and the coefficients m represents the slope of the line and b represents the y -intercept. We can rewrite the slope formula using function notation as m = f(x2) − f(x1) x2 − x1 where (x1, f(x1)) and (x2, f(x2 ... NettetA function is a linear function if it satisfies two properties: Property L1: For every vector v in V and every scalar in. Property L2: For every two vectors u and v in V, A linear function maps zero vector to zero vector: Lemma: If is a linear function then f maps the zero vector of U to the zero vector of V. The image of a linear function is a ...
