F(x) and g(x) were inverse functions, then if f(a) = b, then g(b) = a
f(x) = (5x+1) / x g(x) = x / (5x+1)
f(1) = 6, but g(6) = 6/31 ≠ 1
So, f(x) and g(x) are NOT inverse functions.

Answer:
4x^3-16x^2-28x+40
It will take a while to describe how i got this, but i checked the zeroes are ok.
Answer: 31.25 ft
Step-by-step explanation:
50 / 32 = x / 20
32x = 50(20)
x = 31.25 ft
