Finding Increasing Intervals: Function Analysis with Vertical Line x=0.6

Question

In what interval is the function increasing?

Purple line: $x=0.6$

00:00 Find the domain of increase of the function

00:03 The function increases when X and Y values increase simultaneously

00:06 The function increases up to the green line

00:09 This is the domain of increase

00:14 And this is the solution to the question

Let's remember that a function is increasing if both X values and Y values are increasing simultaneously.

A function is decreasing if X values are increasing while Y values are decreasing simultaneously.

In the graph, we can see that in the domain $x < 0.6$ the function is increasing, meaning the Y values are increasing.

$x<0.6$
