Using Newton's method to approximate the first positive solution to a given equation involves stating a function of the formula for Newton's method for this situation. Which of the following represents this function?
a) ( f(x) = x - f(x)/f'(x) )
b) ( f(x) = x + f(x)/f'(x) )
c) ( f(x) = x - f'(x)/f(x) )
d) ( f(x) = x + f'(x)/f(x) )
