Briana's function uses distance as an input to determine signal strength, but Briana is interested in using signal strength to find a certain distance. Her device reports a signal strength of 25, but Briana wants to know how far away the transmitters are from a cell phone tower.

She can determine the distance by writing the inverse function off(x) = 100/x^2 and using 25 as the input value to the inverse function.

Find the inverse of the function, and use it to evaluate. f^1(25)
