What is one reason why a business would want to review their testing results to refine and improve their quality control process? a. \( \qquad \) \( \qquad \) QUESTION FIVE (20 MARKS) a) Let \( z \) range over the extended \( z \)-plane and the point at infinity. Using the maps \( g_{1}: z \rightarrow z, g_{2}: z \rightarrow \frac{1}{1-z}, g_{3}: z \rightarrow \frac{z-1}{z}, g_{4}: z \rightarrow \frac{1}{z} \) \( g_{5}: z \rightarrow 1-z \) and \( g_{6}: z \rightarrow \frac{z}{z-1} \). Verify that the set of these maps form a group under the composition of mappings.
