If a function

f

satisfies

f\left\{ {f\left( x \right)} \right\} = x + 1

for all real values of

x

and if

f\left( 0 \right) = \frac{1}{2}

, then

f\left( 1 \right)

is equal to

View answer and explanation

Correct option: C

\frac{3}{2}

Option C (3/2) is correct because by using the given condition f{f(x)} = x + 1 and f(0) = 1/2, we can find f(1) by substituting appropriate values.
