As shown in the figure, l1 reflects the relationship between sales revenue and sales volume of a company's products, and l2 reflects

To understand the relationship between the sales cost and sales volume of the company's products, fill in the blanks according to the image:

(1) When the sales volume is 2t, sales revenue = _____ yuan, sales cost = ____ yuan;

(2) When the sales volume is 6t, sales revenue = _____ yuan, sales cost = ____ yuan;

(3) When sales volume equals ___, sales revenue equals sales cost;

(4) When the sales volume is ____, the company makes a profit (revenue is greater than the cost); when the sales volume is _____, the company makes a loss (the revenue is less than the cost);

(5) The function expression corresponding to l1 is _____, and the function expression corresponding to l2 is _____.

PPT on the application of linear functions, the third part: Understanding new knowledge

Knowledge Points Application of Obtaining Information from Charts

Knowledge Points Application of Obtaining Information from Function Graphs

Summarize

This question mainly tests how to use the method of undetermined coefficients to find the relationship between a linear function and the coordinates of the intersection of the function graph and the x-axis. Obtaining the correct information based on the graph is the key to solving the problem.

Using the graph of a linear function to solve practical problems has been a hot topic in the high school entrance examination in recent years. When using the knowledge of a linear function to determine which method is more cost-effective, it is often obtained by observing the graph of the function.

Application of linear function PPT, part 4 content: Class summary

Obtaining the required information from the function graph, and then finding the function expression to solve practical problems and geometric problems is a reflection of the value of function application. This type of question is often combined with some hot issues to test students' comprehensive analysis and problem solving. Ability.
