f(x)=4 x-x^{2}, x \in R

, then

f(a+1)-f(a-1)

is equal to

View answer and explanation

Correct option: B

4(2-a)

Option B (4(2-a)) is correct because it is the simplified expression after evaluating f(a+1) - f(a-1) using the given function.

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\}
