Question

Can somebody help me please

Answer 1

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

(

−

∞

,

∞

)

{

x

|

x

∈

R

}

Since

x

is on the right side of the equation, switch the sides so it is on the left side of the equation.
