Q:
# which of the following pairs of functions are inverses of each other

Accepted Solution

A:

Answer:Option C.Step-by-step explanation:To know if two functions are inverse of each other we need to Plug the first function f (x) into the second one g (x) and simplify. If g[f(x)]=x then f(x) and g(x) are inverses if not, they are not inverses. The correct option is the C, given that:f(x) = 5x - 11 and g(x) = (x+11) / 5Pluggin f(x) into g(x)g[f(x)]= (5x - 11 + 11)/5 = 5x/5 = x
