What is the range of the function$$G(x) = |x+1|-|x-1|~?$$Express your answer in interval notation.s
Help would be much appreciated.
Note that when x is any negative.....the expression will evaliuate to all values on [ -2, 0)
When x = 0 the function evaluates to 0
When x is any positive.....the function evaluates to all values on (0, 2]
This graph is continuous for all x
So the range is [ -2, 2 ]
Here's a graph :
