Explanation:
F(x) = 0 when x≥0x when x<0 and F1(x) = -xwhenx>00 whenx≤0
Therefore, replacing x by (−x) in above functions, we get
F(-x) = 0 when x≤0-x when x>0 and F1(-x) = x when x<00 when x≥0
Clearly, F1(x) = F(−x), hence, option (b) is the correct choice.
Alternate solution: F1(-2) = 0 = F(2) and F1(2) = −2 = F(−2).
So the correct option is (b), i.e. F1(x) = F(−x).
Hence, option (b).
