Q4 of 41 Page 44

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.
