Function Table Analysis: Finding Increasing Intervals from -4 to 14

Question

In which domain is the function increasing?

f(x)x-44-1100116210014-78-9

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
00:10 From this point the function starts to rise
00:16 At this point the function decreases again
00:23 We will deduce from this the domain of increase
00:32 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 10 > x > 0 the X values and Y values increase simultaneously.

Therefore, the function increases in the domain where

10 > x > 0

Answer

10 > x > 0
