How do you find the positive/negative intervals of f(x) = 3/x + 5?

        [] The positive interval is where the function is above the x-axis, and the negative interval is where the function is below the x-axis.

        [] To find it, we can graph the function

                    () See attached

        [] When the function is equal to less than 0, it'll be negative, otherwise it is positive

Have a nice day!

  I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
