ANTONII [103]

Answer:

F(k)= \frac{9}{5}(k - 273.15) + 32

Given

F(c)= \frac{9}{5}c + 32

C(k) = k - 273.15

Required

Function from K to F

This implies that, we calculate F(k)

Given that:

F(c)= \frac{9}{5}c + 32

Substitute c(k) for c

F(c(k))= \frac{9}{5}c(k) + 32

Substitute: C(k) = k - 273.15

F(c(k))= \frac{9}{5}(k - 273.15) + 32

Hence:

F(k)= \frac{9}{5}(k - 273.15) + 32
