a) $f^{-1}(2)$ = 6 b) $f^{-1}(5)$ = 2 c) $f^{-1}(6)$ = 0
a) To find $f^{-1}(2)$, find where f(x) = 2 is on the graph. The coordinates are (6,2). Therefore $f^{-1}(2)$ = 6 b) To find $f^{-1}(5)$, find where f(x) = 5 is on the graph. The coordinates are (2,5). Therefore $f^{-1}(5)$ = 2 c) To find $f^{-1}(6)$, find where f(x) = 6 is on the graph. the coordinates are (0, 6). Therefore $f^{-1}(6)$ = 0
