The function ‘t’ which maps temperature in degree Celsius into temperature in degree Fahrenheit is defined by

Find (i) t(0) (ii) t(28) (iii) t(–10) (iv) The value of C, when t(C) = 212.

Given:

(i) t(0)



t(0) = 32


(ii) t(28)





(iii) t(-10)



t(-10) = -18 + 32 = 14


(iv) t(C) = 212







Value of C, when t(C) is 212 = 100.
