# Visualizing marginal utility MU and total utility TU functions

This video shows how we can visualize marginal utility (MU) and total utility (TU) functions graphically.

• Is the line for marginal utility the first derivative of the curve for total utility with respect to the number of tennis balls (x)?
• That is mostly correct. Remember that the definition of marginal utility is the benefit added by each additional unit, which is a rate of change. However, marginal utility is usually measured in whole units and is not continuous, so you couldn't say that it is a curve
• How much tennis can one person play? ? ? ? ?
• A lot or untill they continuously forcefully play until their body says I'm done and they pass out from exhaustion :)
• Is the area under the marginal utility curve the total utility?
• I think it would be because the MU curve would represent the change in total utility at each instant, so I think MU would be the derivative of TU.

• for the marginal utility "units" could be satisfaction.
