The domain of definition of the function

f\left( x \right){ = ^{7 - x}}{P_{x - 3}},

View answer and explanation

Correct option: C

\left\{ {3,\;4,\;5} \right\}

Option C (

\left\{ {3,\;4,\;5} \right\}

) is correct because the domain is determined by the conditions 7-x >= 0, x-3 >= 0, and 7-x >= x-3, which lead to x being 3, 4, or 5.
