You are given the following function.
(a) Find the derivative of the function using the definition of derivative.
(b) Give the domain of the function.
c) Give the domain of derivative of function?
use the quotient rule
dy/dx = [(1-8x)(1) - (8+x)(-8)]/(1-8x)^2
= ... (you simplify it)
b) domain of f(x) is any real number, x not equal to 1/8
c) same as b)
