Question

The function ‘t’ which maps temperature in degree Celsius into temperature
in degree Fahrenheit is defined by(C) = 9/5 + 32. Find

(i) t (0)

(ii) t (28)

(iii) t (–10)

(iv) The value of C, when t(C) = 212

Answer 1

The given function is () = 9/ 5 + 32.
Therefore,

Thus, the value of t, when t(C) = 212, is 100.
