Find the monotone interval of function f (x) = x + 1 / x + 1, and find its maximum and minimum Help!

Find the monotone interval of function f (x) = x + 1 / x + 1, and find its maximum and minimum Help!


(- ∞, - 1] increase [- 1,0) decrease (0,1] decrease [1, + ∞] increase
Maximum f (- 1) = - 1 minimum f (1) = 3



How to solve a problem of linear equation
The linear equation through a (- 3,0), B (0,4)
The answer is: - X / 3 + Y / 4 = 1
Excuse me, is this the intercept type? But the title does not clearly state a = x1, B = Y2?


A is on the x-axis, B is on the y-axis
So you can use intercept directly
