f(x)=3 x-5

, then

f^{-1}(x)

View answer and explanation

Correct option: B

is given by

\frac{x+5}{3}

Option B (is given by

\frac{x+5}{3}

) is correct because it represents the inverse function of f(x) = 3x - 5.

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\}
