Question

Find the absolute minimum on the interval [-2, 2] of the function f (x) = x 3 + 3x 2 + 1

Answer 1

You need to look at
1) f(-2)
2) f(2)
3) f(any extrema) To Find extrema set the derivative = 0.

whichever of these results in the lowest value is your absolute minimun

Answer 2

I got f(0)=1
