Question

I need calculus help 2 questions.

Answer 1

here is the first one

Answer 2

well you need to take the derivative to begin with. this will give you the slope which you can set to zero to see what your graph hits maximums and minimus

Answer 3

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

Answer 4

is that the derivative?

Answer 5

yes

Answer 6

ok set it to zero

Answer 7

x=1,-1

Answer 8

now what?

Answer 9

Those are our critical points.

Answer 10

right now you can place them on a numberline

Answer 11

aright now you want to check if the graph is increasing or decreasing between each critical point. Kind of like a limit
