I think this is what you mean:
Look at the sign of the derviative in the interval
you will find that it is a local max at and local min at
Therefore the function is increasing from and and decreasing on
Hi everyone i was just wondering if anyone could help with this differentiation question it is :
Use differentitation to find the coordinates of the stationary points on the curve.
Y= x + 4/x
And determine whether each stationary point is a maximum point or minimum point.
Find the set of values of x for which y increase as x increases.
Even if you can help with a small part of the question i would be grateful
