Find inverse functions by solving f(x)=c for simple invertible functions and writing inverse expressions.

Interpret an inverse function value in context

Problem

\(A\) maps a square's nonnegative side length to its area. Interpret \(A^{-1}(49)=7\) by identifying both inverse units, giving the equivalent equation for \(A\), and explaining why the nonnegative branch determines the side length.
