Answer:
Third answer is correct
Step-by-step explanation:
As we can easily tell from the graphs one of the functions f(x) = -1, f(x) = 4 (the lower line is at -1 and the other (upper) line is at 4 on the y axis). So only the last two answers can be correct.
The lower line starts at -3 and ends at 3, so near f(x) = -1, x is more than -3 and less than 3 (also we can write it as -3 < x < 3). Therefore the third answer is correct.
