The answer is A. –4 and 4
The symbol IxI reads as 'the absolute value of x. It means that all integers including negative integers that is expressed by x be written in absolute value. Since the equation is |x| = 4 and substituting the absolute values of x as integers –4 and 4, then the integers –4 and 4 represents the absolute value of x as true.
