To graph indifference curves from utility functions, you can plot different combinations of two goods that give the same level of satisfaction or utility to a consumer. Each indifference curve represents a different level of utility, with higher curves indicating higher levels of satisfaction. By using the utility function to calculate the level of satisfaction at different combinations of goods, you can plot these points to create the indifference curves on a graph.
. Cardinal Approach refers that you can calculate or Measure the utility (degree of satisfaction) Numerically, while According to ordinal approach you can not measure the utility numerically. 2. Cardinal Approach follow the Law of Diminishing Marginal Utility while Ordinal Approach follow the Indifference Curve. 3.Cardinal Approach Emphasis on units while ordinal approach is based on rank.
