f(x)x-210-1.58-0.560112133183.520526

Video Solution

Solution Steps

00:00 Find the domain of increase of the function
00:04 The function increases when X and Y values increase simultaneously
00:09 From this point the function begins to increase
00:21 We'll deduce from this the domain of increase
00:30 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 > -0.5 the X values and Y values increase simultaneously.

Therefore, the function increases in the domain where

x > -0.5

Answer

x>-0.5
