Function

f: R \rightarrow R, f(x)=x^{2}+x

View answer and explanation

Correct option: D

Many-one into

Option D (Many-one into) is correct because the function

f(x) = x^2 + x

is many-to-one and its range is not the entire set of real numbers.

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\}
