Can you construct a linear function $L: \mathbb{R}^3 \rightarrow \mathbb{R}$ such that $L\left(\begin{array}{r}1 \\ -1 \\ 0\end{array}\right)=1, L\left(\begin{array}{r}1 \\ 0 \\ -1\end{array}\right)=4$, and $L\left(\begin{array}{r}0 \\ 1 \\ -1\end{array}\right)=-2$ ? If yes, find one. If not, explain why not.

Key Concepts

Linear Transformations

A linear transformation between vector spaces is a function that preserves vector addition and scalar multiplication. This property means that the function is completely determined by its action on any basis of the domain. In constructing such a function, one often defines it via its values on a set of linearly independent vectors that span the domain.

Basis and Coordinate Representation

A basis of a vector space is a set of linearly independent vectors that span the space. When a linear transformation is defined on the basis vectors, its value on any other vector can be determined by expressing that vector as a linear combination of the basis elements. This process is essential in constructing specific linear functions that satisfy given conditions.

System of Linear Equations

Constructing a linear function to meet specific criteria typically involves formulating a system of linear equations based on the images of selected vectors under the function. Solving this system reveals whether a function meeting all the constraints exists and, if so, determines its coefficients. The consistency of the system ensures that the required linear transformation can be defined.
