Question

the function f(x) is invertible. find $f^{-1}(65)$.\
\

x	f(x)	\
----	------	\
25	-99	\
35	94	\
45	-50	\
55	65	\
65	-46	\

\
$f^{-1}(65) = \square$\

Explanation:

Step1: Recall inverse function definition

The inverse function \( f^{-1}(y) \) gives the \( x \) such that \( f(x) = y \). So we need to find \( x \) where \( f(x) = 65 \).

Step2: Look at the table

Check the table for the row where \( f(x) = 65 \). From the table, when \( x = 55 \), \( f(x) = 65 \).

Answer:

55
