I have struggled to understand the definition of the part c , please explain it step by step, thank you!

Consider the inverse demand function P = 6e'0'25'3. a. Use the total differential to nd the total derivative dTR/dQ, given the denition of total revenue as TR = P0. b. Check the answer by direct substitution. c. What is the economics term for dTR/dQ? According to your answers, does it depend only on the market price? If not, what else does this term depend on? Give a verbal interpretation of your answers. c. TR/dQ is marginal revenue. From % = P + 0% we can see that the marginal revenue has two components: the change in revenue from selling another unit at price P; the change in revenue from the price reduction that . . up . . may be necessary to sell one more unit, which equals Q E ( the price reduction multiplied by the original quantity sold). This is negative since %
