Question

If a function 'f' is an identity function and f(6) = a, then find the value of a.

• A. $\frac{1}{6}$
• B. $-\frac{1}{6}$
• C. 6
• D. -6

Answer 1

The correct option is C 6

A function f : R$\to$R is an identity function if f(x) = x.
Here, given 'f' is an identity function.
$\therefore$ f(6) = 6
$\therefore$ a = 6
