The utility function in this graph is bowed downward (convex), which is different from the usual case where the utility function is bowed upward (concave). This means that Dexter experiences diminishing marginal utility at a decreasing rate as his wealth increases. As a result, the optimal choice for Dexter may be different from what we would expect under the usual assumption of a concave utility function.
