Need some help with the following problem:
Find the maximum and minimum values of the function on the given interval.
Y=3-x/x^2+9x.....Interval [3,10]
Thank You

Simplify your formula to...
$\displaystyle y = 3 - \frac{1}{x + 9}$.
Find the derivative.
Set this equal to 0. Solve and only keep values that are contained in [3,10].
But that's not all.
At the endpoints of the interval, you need to figure out if they are 'maximums' or 'minimums' and by that I don't mean they are stationary points.
See the function of $\displaystyle x^3$ I have attached. At the endpoints (which are indicated by the vertical black lines) we have a 'maximum' at the right hand one (near x=5) and a 'minimum' at the left hand one (near x=-5).
These are only maxs and mins on the interval.
