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.
