WebFrom (a) and (b), we know that f is invertible if and only if it’s bijective.) Pf. We have h “ id Y ˝ h “pg ˝ fq˝h “ g ˝pf ˝ hq“g ˝ id Y “ g. (d) Suppose f : X Ñ Y and g : Y Ñ Z are both bijective functions. Then g ˝ f is also bijective. Pf. Since f and g are bijective, they have two-sided inverses f´1 and g´1. Gaussian elimination is a useful and easy way to compute the inverse of a matrix. To compute a matrix inverse using this method, an augmented matrix is first created with the left side being the matrix to invert and the right side being the identity matrix. Then, Gaussian elimination is used to convert the left side into the identity matrix, which causes the right side to become the inverse of the input matrix.
