4. Consider Jian Huan (JH) and Juan Camilo (JC) who are loss averse with value function v(x). JH is an optimist and believes that he will receive a raise of 6,400. JC is a pessimist and believes he won't receive a raise. In fact, at the end of the year, both receive a raise of 5,000. Assume both have the following value function: v(x) a for gains (0) 2x for losses ( 5000, given that the value function will change based on these situations. If you are going to check for individual values of b, you can focus on the range from 0 to 10,000, in multiples of 500. If you are using a calculator like Desmos.com, you can plot a function for a specific range (for example b < 5000) by adding the following after your equation: "{
