Step 1

We are given a function as

Step 2

We can find derivative and then set top and bottom term to 0

and then we solve for x help_outlineImage Transcriptionclose1 f(x)x1) d 1 f'(x)= d(x+1 (x+1)) dx 2 1 (x1) 2 f'(x) (x1) (x 10 (r1)0 fullscreen
Step 3

Now, we can draw a number line

and locate x=-1

and then we can check sign of first derivative on each intervals ...
