Question

If the domain of $h\left(x\right)$ is $R-A$ , where ${}^{\prime }{R}^{\prime }$ is set of real number then the product of all elements in set ${}^{\prime }{A}^{\prime }$ is

• A. $0$
• B. $e^2$
• C. $\frac{1}{e^2}$
• D. $e^4$

Answer 1

The correct option is B $e^2$

product of all elements in set

$A^{\prime }=e\times e=e^2$

where demain of $h\left(x\right)=R-A$ & $R$ is a set of real numbers
