Ok. here's the problem
f(x)=x-6, h(x)=2x^3-6, g(x)= the square root of (x+6) --i didnt know how to type a square root sign.
Find the rule for the function f-h
-----
g
I dont know what "find the rule" means. I thought it meant plug in the values and simplify but when i put in the answer in my online homework it tells me i'm wrong. i dunno what to do so please help me out! Thanks
btw its supposed to be f-h all divided by g

(f-h)/g
= (x-2x^3)/√(x+6)
= x(1-2x^2)√(x+6)/(x+6)

OK
Lets try
((x-6) - (2x^^3 -6)) / (x + 6)
Or
(-2X^^3 + X - 6 + 6) / (X +6)
OR
(X-2X^^3)/(X + 6)
OR
X (1-2x^^2) / (X + 6)
