f(x)=x^7(x+2)^2

On which two intervals is the function increasing (enter intervals in ascending order)?

Find the region in which the function is positive

Where does the function achieve its minimum?

**GanonTEK**, Friday, March 13, 2009 at 9:55pmit's turning points are when

[1] x*7 = 0 or x = 0

[2] (x+2)^2 = 0 or x - -2

The graph is increasing when

(-12 to -2) and (0 to 10)

To work this out find the turning points by finding f'[x]=0

ok hope that helps
