A linear map (or transformation, or function) transforms elements of a vector space called domain into elements of another vector space called codomain. Being bijective, \(f\) is also injective, so every \(t\) has no more than one pre-image. : the range of temperature within which austenite forms or disappears when ferrous alloys are heated or cooled.

We solve by finding the corresponding 2 x 3 matrix A, and find its null space and column span. The matrix of \(T^{-1}\) denoted as \(A\) needs to satisfy \[A\left[ \begin{array}{rrr} 1 & 0 & 0 \\ 1 & 0 & 1 \\ 0 & 1 & 0 \end{array} \right] =\left[ \begin{array}{rrr} 1 & 0 & 1 \\ 0 & 1 & 0 \end{array} \right] \nonumber \] and so \[A=\left[ \begin{array}{rrr} 1 & 0 & 1 \\ 0 & 1 & 0 \end{array} \right] \left[ \begin{array}{rrr} 1 & 0 & 0 \\ 1 & 0 & 1 \\ 0 & 1 & 0 \end{array} \right]^{-1}=\left[ \begin{array}{rrr} 0 & 1 & 0 \\ 0 & 0 & 1 \end{array} \right] \nonumber \], Note that \[\left[ \begin{array}{rrr} 0 & 1 & 0 \\ 0 & 0 & 1 \end{array} \right] \left[ \begin{array}{c} 1 \\ 1 \\ 0 \end{array} \right] =\left[ \begin{array}{c} 1 \\ 0 \end{array} \right]\nonumber \] \[\left[ \begin{array}{rrr} 0 & 1 & 0 \\ 0 & 0 & 1 \end{array} \right] \left[ \begin{array}{c} 0 \\ 0 \\ 1 \end{array} \right] =\left[ \begin{array}{c} 0 \\ 1 \end{array} \right] \nonumber \] so the restriction to \(V\) of matrix multiplication by this matrix yields \(T^{-1}.\).

Ker(L) is the same as the null space of the matrix A. Then the image of \(T\) denoted as \(\mathrm{im}\left( T\right)\) is defined to be the set \[\mathrm{im}\left( T\right) = \left\{T (\vec{v}):\vec{v}\in V\right\}\nonumber \] In words, it consists of all vectors in \(W\) which equal \(T(\vec{v})\) for some \(\vec{v}\in V\). Therefore \(\left\{ \vec{u}_{1},\cdots ,\vec{u}_{s},\vec{v}_{1},\cdots ,\vec{v} _{r}\right\}\) is a basis for \(V\) and so \[n=s+r=\dim \left( \ker \left( T\right) \right) +\dim \left( \mathrm{im}\left( T\right) \right)\nonumber \]. For range (T), just row reduce A to Echelon form, the remaining non-zero vectors are basis for Range space of T. To find the range(image) of T, find the transpose of the matrix first and then reduce the transposed matrix to an echelon form, the remaining non zero matrix becomes the basis for the range and the dimension becomes the rank. However, with a little practice and perseverance, anyone can learn to love math! Which means that all of the constants are zero since these are linearly

SSD has SMART test PASSED but fails self-testing.
In the example where \(L(x,y)=(x+y,x+2y,y)\), the map \(L\) is clearly not surjective, since \(L\) maps \(\Re^{2}\) to a plane through the origin in \(\Re^{3}\). \]
