In this question, we want to determine whether this statement is true or false.
00:04
It says the increasing intervals minus infinity to 3 union with 2 to infinity.
00:12
Let's draw the number line.
00:15
Now, 0 is here, 2 is here, and 3 is here.
00:19
The numbers to the right of the number lines are very large numbers.
00:24
So it's plus infinity over here.
00:28
And the numbers going to the leftmost side is very large negative numbers, so minus infinity.
00:37
Now, for number line, we always read from left to right.
00:42
That is the small numbers are on the left, the large numbers are on the right.
00:48
So it's in ascending order from left to right, or what we call increasing order from left to right...
