Question

Which graph is the solution to |x| > 10?

Answer 1

|x| > 10

x < - 10 or x > 10

The plot is open dots on -10 and 10 and shading to the left of -10 and to the right of 10.

Answer is the third choice.

Answer 2

The correct option is 3.

Explanation:

The given inequity is

`|x|>10`

If an inequity is defined as

`|x|>a`

then x<-a and x>a.

In the given inequality a=10, so the solution of the given inequlity are

x<-10 and x>10.

It means all the numbers less than -10 and more than 10 are in the solution set. We have open circle at 10 and -10 because 10 and -10 are not included in the solution set.

Therefore the correct option is 3.
