For each function in 9a and b, find the value of the expressions in i to iv.

Question:

For each function in 9a and b, find the value of the expressions in i to iv.
a. f (x) = 6.34x - 140
b. f (x) = 1.8x + 32
i. f-1(x)
ii. f(f-1(15.75))
iii. f-1(f (15.75))
iv. f(f-1(x)) and f-1( f (x))
The equation in 9b will convert temperatures in °C to temperatures in °F. You will use either this function or its inverse in Exercise 10?
