What is Reduced Row Echelon Form? (9 Powerful Examples)

WebMar 24, 2024 · For any function f:A->B (where A and B are any sets), the kernel (also called the null space) is defined by Ker(f)={x:x in Asuch thatf(x)=0}, so the kernel gives the elements from the original set that are mapped to zero by the function. Ker(f) is therefore a subset of A The related image of a function is defined by Im(f)={f(x):x in A}. In linear algebra, a matrix is in echelon form if it has the shape resulting from a Gaussian elimination.
