Question

Assume that the domain of
f and f^−1 is (−∞, ∞). Solve the equation for x using the given information.

(a) 7 + f^−1(x − 6) = 9; f(2) = 5


(b) 4 + f(x + 7) = −3; f^−1(−7) = 0

Answer 1

\[\begin{align*}
7+f^{-1}(x-6)&=9\\
f^{-1}(x-6)&=2\\
f(f^{-1}(x-6))&=f(2)\\
x-6&=f(2)
\end{align*}\]

Answer 2

thanks ur the best
