Question

Solution

Correct option is

x  [-2, 0)  (0, 1)

{as we know ; log a x is defined when x, a > 0 and a ≠ 1 also log 1= 0.}

Thus, log10 (1 – x) exists when,  1 – x > 0                          …(i)

.   1 – x > 0 and 1 – x  1   … (ii)

⇒                                                 x < 1 and x  1               …(iii)

x + 2 ≥ 0

or                                                      x ≥ -2

exists when (iii) and (iv) both holds true.

⇒                -2 ≤ ≤       and    x
