The domain of the function

f(x)=\frac{1}{\sqrt{|x|-x}}

View answer and explanation

Correct option: B

(-\infty, 0)

Option B

((-\infty, 0))

is correct because the expression inside the square root,

|x|-x

, must be greater than zero, which is only true when x is negative.

f:(-\infty, 2] \longrightarrow(-\infty, 4]

f(x)=x(4-x)

f^{-1}(x)

g(f(x))=|\sin x|

f(g(x))=(\sin \sqrt{x})^2

f:\left( {2,\;3} \right) \to \left( {0,\;1} \right)

f\left( x \right) = x - \left[ x \right]

{f^{ - 1}}\left( x \right)

f: R \rightarrow R

f(x)=x^4

f(x)=(x+1)^2-1(x \geq-1)

S=\left\{x: f(x)=f^{-1}(x)\right\}
