1.Relation and Function
normal
Domain of the function $f(x)\,=\,\frac{1}{{\sqrt {(x + 1)({e^x} - 1)(x - 4)(x + 5)(x - 6)} }}$
A
$( - \infty , - 5) \cup ( - 1,4) \cup (6,8)$
B
$( - \infty , - 5) \cup ( - 1,0) \cup (0,4) \cup (6,\infty )$
C
$( - 5, - 1) \cup (0,4) \cup (6,\infty )$
D
$( - \infty , - 5) \cup ( - 1,4) \cup [6,\infty )$
Solution
$(x+1)\left(e^{x}-1\right)(x-4)(x+5)(x-6)>0$
$\mathrm{CP}^{\prime}$ $s$ are $\{-1,0,4,-5,6\}$
$\mathrm{x} \in(-5,-1) \cup(0,4) \cup(6, \infty)$
