Answer:
yes
Step-by-step explanation:
f(x) = y = 4 - 7x/4
7x/4 + y = 4
7x/4 = 4 - y
7x = 4(4-y)
x = 4(4-y)/7 = 16/7 - 4y/7
renaming to regular function convention (with x as input variable and y as function result) :
inverse function f(x) = y = -4x/7 + 16/7 = g(x)
so, yes, they are inverses of each other.
