The formula for converting from Fahrenhe...

The formula for converting from Fahrenheit to Celsius temperatures is y = `(5x)/(9)-(160)/(9)`. Find the inverse of this function and determine whether the inverse is also a function.

Text Solution

Verified by Experts

The correct Answer is:
Replacing y by x, we get ` f^(-1) (x) = (9x + 160)/(5) = (9x)/(5) + 32 `
