Average and marginal profit Let C(x) represent the cost ofproducing x items and p(x) be the sale price per item if x items aresold. The profit P(x) of selling x items is P(x) = xp(x) - C(x)(revenue minus costs). The average profit per item when x items aresold is P(x)/x and the marginal profit is dP/dx. The marginal profitapproximates the profit obtained by selling one more item, given that x items have already been sold. Consider the following cost functions Cand price functions p.a. Find the profit function P.b. Find the average profit function and the marginal profit function.c. Find the average profit and the marginal profit if x = a units are sold.d. Interpret the meaning of the values obtained in part (c).C(x) = -0.04x2 + 100x + 800, p(x) = 200, a = 1000
Transformation of Graphs
The word ‘transformation’ means modification. Transformation of the graph of a function is a process by which we modify or change the original graph and make a new graph.
Exponential Functions
The exponential function is a type of mathematical function which is used in real-world contexts. It helps to find out the exponential decay model or exponential growth model, in mathematical models. In this topic, we will understand descriptive rules, concepts, structures, graphs, interpreter series, work formulas, and examples of functions involving exponents.
Average and marginal profit Let C(x) represent the cost of
producing x items and p(x) be the sale price per item if x items are
sold. The profit P(x) of selling x items is P(x) = xp(x) - C(x)
(revenue minus costs). The average profit per item when x items are
sold is P(x)/x and the marginal profit is dP/dx. The marginal profit
approximates the profit obtained by selling one more item, given that x items have already been sold. Consider the following cost functions C
and price functions p.
a. Find the profit function P.
b. Find the average profit function and the marginal profit function.
c. Find the average profit and the marginal profit if x = a units are sold.
d. Interpret the meaning of the values obtained in part (c).C(x) = -0.04x2 + 100x + 800, p(x) = 200, a = 1000
