The inverse fun. of the given fun. does not exist.

Explanation:

Let $y = f (x) = x^{2} - 6 x + 4 = x (x - 6) + 4 .$ $y=f(x)=x^2-6x+4=x(x-6)+4.$

Hence, $f (0) = 4, f (6) = 4$ $f(0)=4, f(6)=4$ , indicating that the fun. $f$ $f$ is not an injection, i.e., $f$ $f$ is not $1 - 1$ $1-1$ .

The inverse of a given fun. exists $\Leftrightarrow$ $iff$ It is bijective (injective = $1 - 1$ $1-1$ , surjective=onto)

Therefore, we can not find its inverse function.
