Step-by-Step Solution

Given two points A A and B B on a plane, we need to determine if a function can pass through these points such that it is increasing.

Consider the definition of an increasing function: For the function to be increasing, if x2>x1 x_2 > x_1 , then it must satisfy y2>y1 y_2 > y_1 .

Let's apply this to the problem:

  • Let the first point be A=(x1,y1) A = (x_1, y_1) and the second point be B=(x2,y2) B = (x_2, y_2) .
  • The function is increasing between these two points if x2>x1 x_2 > x_1 and y2>y1 y_2 > y_1 .

From the information provided, since the graph indicates that the point corresponding to B B is vertically above A A , it follows that:

  • The x x -coordinates are ordered such that x2>x1 x_2 > x_1 .
  • The y y -coordinates satisfy y2>y1 y_2 > y_1 .

Both necessary conditions hold, so it is indeed possible to create an increasing function passing through these two points.

Therefore, the answer to the problem is Yes.

Yes
