C = ( 5 / 9 ) ( F - 32 ) Multiply both sides by 9
9 C = 5 ( F - 32 ) Divide both sides by 5
( 9 / 5 ) C = F - 32 Add 32 to both sides
( 9 / 5 ) C + 32 = F - 32 + 32
( 9 / 5 ) C + 32 = F
F = ( 9 / 5 ) C + 32
The function C = (5/9)(F - 32) expresses the Celsius temperature as a function of the Fahrenheit temperature. Find the inverse function. What is it used for?
