Which of the following is NOT  a polynomial function?

Alice, Bob, and Charlie are each advocating for different software solutions to be purchased for their company. To reach a decision, they plan to conduct a weighted scoring analysis. They conduct preliminary financial analysis to estimate return on investment (ROI) for the different software. Alice’s preferred software has an ROI of 20%, Bob’s software has an ROI of 10%, and Charlie’s software has an ROI of 15%. In terms of usability, Bob’s software is the easiest to use straight out of the box, while Alice’s software has a steep learning curve. Charlie’s software falls somewhere in between. As expected, the software that is hardest to use offers the most features. While Bob’s software is the easiest to use, it has slightly fewer features than Charlie’s and significantly fewer than Alice’s, whose software provides the most features and functionalities. All three criteria are almost equally important for their decision. But they can’t decide whether ease of use or features should have higher weight. They do agree that ROI is more important than either of the other two. So, they decide on criteria weights of 30%, 30%, and 40%, ensuring weights sum to 100%. Next, they decide to assign scores of 25, 50, and 75 for low, medium, and high performance on each criteria. Help Alice, Bob, and Charlie fill out their weighted scoring sheet and decide on a software by interpreting it for them. General weighted scoring sheet: Criteria Weight (in %age) Option A Option B Option C Criteria 1 weight for criteria 1 score of option A on criteria 1 … … Criteria 2 weight for criteria 2 … … … Criteria 3 weight for criteria 3 … … score of option C on criteria 3 sum of all weights sum of (score * weight) on each criteria, for option A … … Fill in the table below: Criteria Weight Alice’s software Bob’s software Charlie’s software ROI item 1 item 2 item 3 item 4 Ease of use item 5 item 6 item 7 item 8 Features item 9 item 10 item 11 item 12 Totals: item 13 item 14 item 15 item 16 Item 1 = _______ item 2 =  _______ item 3 =  _______ item 4 =  _______ item 5 =  _______ item 6 = _______ item 7 = _______ item 8 =  _______ item 9 =  _______ item 10 =  _______ item 11 =  _______ item 12 =  _______ item 13 =  _______ item 14 =  _______ item 15 =  _______ item 16 =  _______ Based on the above numbers, whose software should be chosen? Alice, Bob, or Charlie? Write the name of the person:   _______
