You can put this solution on YOUR website! Here is a graph of the function
:
:
we are given that x lies in interval -1, 1
:
we need to know if this is an open interval or a closed one
:
I assume it is a closed interval
:
looking at the graph, we can see that the function has a minimum at x=1 on the closed interval [-1, 1]
:
min on [-1, 1] = -1 -6 +16 = 9
