The image displays a blackboard with several mathematical problems written on it. The problems are numbered and seem to be from different sections of mathematics, including functions and equations. There are also some graphs drawn on the board. The overall context appears to be a classroom setting.

Mathematical Problems on the Blackboard

The image shows a blackboard with several mathematical problems. Here's a breakdown of the visible problems:

• Column I:
• 1) $$ y = \frac{8}{x} $$
• 2) $$ y = -x-5\sqrt{x} $$
• 3) $$ y = ... $$
• Followed by a graph with axes and plotted points.
• Column II:
• 1) $$ y = -2x^2 $$
• 2) $$ \frac{3}{x} = x^3 $$
• Column III:
• 1) $$ y = -\frac{6}{x} $$
• 2) $$ \frac{1}{2}x^2 = \sqrt{x} $$
• Column IV:
• 1) $$ y = 2x^2 $$
• 2) $$ \frac{5}{x} = -x+6 $$

The problems involve various types of functions, including rational, radical, quadratic, and exponential functions, as well as equations. There is also a coordinate plane with a plotted function, likely representing one of the problems.

Additional elements in the image include a phone screen displaying the blackboard, classroom desks and chairs, and some stationery items in the background.
