Finding the Inverse Function of a Quadratic Function What we want here is to find the inverse function – which implies that the inverse MUST be a function itself. Otherwise, we got an inverse that is not a function. Not all functions are naturally “lucky” to have inverse functions. This happens in the case of quadratics because they all … Inverse of Quadratic Function Read More » Compute the following matrix product modulo 26: Expert Answer 83% (6 ratings) Previous question Next question Get more help from Chegg. To get the inverse key matrix, we now multiply the inverse determinant (that was 19 in our case) from step 1 by each of the elements of the adjugate matrix from step 2. Then we take each of these answers modulo 26. Multiplying the inverse of the determinant by the adjugate matrix gets the inverse key matrix. determinant of the key matrix must not have any common factors with the modular base used in the encryption and decryption. The modular base corresponds to the number of symbols being used in the encryption. For example, if we use the letters A-Z as our available symbols, then the modular base of the encryption is 26.
