Question

The function 't' which maps temperature in degree Celsius into temperature in degree Fahrenheit is defined by $t(C) = \frac{9c}{5} + 32.$ Find t(0)

Answer 1

f (Fahrenheit) = 9/5*C + 32
Which means, at Celsius = 0° C
Fahrenheit = 9/5(0)+32 = 32 F.

Answer 2

The function t which maps temperature I. degree Celsius into temperature in degree Farhenhiet is defined by
$\bf{t(C)=\frac{9c}{5}+32}$

here, t(C) denotes farhenhiet and C denotes Celsius.
you should under that , C is independent variables and t(C) is dependent variable because value of t(C) depends on C.
so, we can say that. value of C is domain and value of t(C) is range of the given function.

now come to the question,
we have to find t(0)
here 0 in place of C .
hence, we have to put C = 0 in the given function
so, t(0) = 9 × 0/5 + 32 = 0 + 32 = 32°F
