The temperature, K, in Kelvin, for a given temperature in degrees Fahrenheit, x, can be calculated using the formula:
K(x) = (x – 32) + 273
A student was finding the inverse of the equation and produced the
following work:
Step 1
C
Step 2
= (y – 32) + 273
2 – 273 = (y – 32)
f (x – 273) = y - 32
K-1(x) = {(2 – 273) + 32
Step 3
Step 4
Which of the following is TRUE?
