Verify if 1/2x-2 and g(x) = 2x + 4 are inverses

Mathematics
1 answer:
Triss [41]3 years ago
5 0
They are inverses if f( (g(x)) = x

f((g(x)) =  (1/2) (2x + 4) - 2  = x + 2 - 2 = x

so this proves that g(x) is the inverse of f(x)

the other inverse g((f(x))  should also be = x

8x/8=88000/8
x=$11000
