Hello can someone please help me in these question please?

Answer 1

Answer:

Answer: B

Step-by-step explanation:

$f(x) = \frac{12}{x} - 18$

let its inverse be m :

$m = \frac{12}{x} - 18 \\ \\ m + 18= \frac{12}{x} \\ \\ x = \frac{12}{m + 18} \\ \\ { \boxed{ \boxed{f {}^{ - 1}(x) = \frac{12}{x + 18} }}}$
