Thread: finding prime,max and min point of a function

f(x) (x^2-2x+1)/(x+1)

1) whats f prime of f(x)
2)state the values of x for which f(x) is (i) increasing and (ii) decreasing
3) the coordinates of any relative max and min point....

hi

(1) Have you tried the quotient rule ?

(2) When f'(x)>0 , the function f(x) is increasing and vice versa .

(3) Solve f'(x)=0 , substitute the values of 'x's into the original equation to get the 'y' s . Then you have your points .
