the distance from mercury to the sun is almost 4 x 10^7 miles. the distance from Saturn to the sun is just over 9 x 10^8 miles, estimate about how many times further Saturn is from the sun than mercury

The range is the set of 'y' values that result from the given domain .
Since the absolute value of any real number is a positive, the range is all the real numbers less than or equal to 0.
 
We can see this by placing x = 1 and hence getting 0.
                                               x  = 1  and we get -2
