f(x+1)=x^{2}-3 x+2

, then

f(x)

is equal to:

View answer and explanation

Correct option: D

x^{2}-5 x+6

Option D (

x^{2}-5 x+6

) is correct because by substituting

x-1

into the given function, we can find the expression for

f(x)

Practice All Chapter MCQs →

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\}
