Function Analysis: Finding Increasing Intervals in Domain [-2, 5]

Question

In which domain is the function increasing?

f(x)x-210-1.58-0.560021353.5759

Video Solution

Solution Steps

00:00 Find the domain of increase of the function
00:03 The function increases when X and Y values increase simultaneously
00:12 From this point the function starts to increase
00:20 We will deduce from this the domain of increase
00:27 And this is the solution to the question

Step-by-Step Solution

Let's remember that the function increases when X values and Y values increase simultaneously.

On the other hand, the function decreases when X values increase and Y values decrease simultaneously.

According to the given value table, we can see that in the domain where x > 0 the X values and Y values increase simultaneously.

Therefore, the function increases in the domain where

x > 0

Answer

x>0
