Best ResponseYou've already chosen the best response.0First Derive f(x). \[f \prime{(x)}=40x^{(7/3)}\] Now find where the derived of f is zero... (extreme point(s)). You do this by setting the derived equal zero. The extreme must be horisontal (0). Solve(0= 40x^{(7/3),x) The global MINIMUM extreme is lokatedf at (0,0) To check it you can enter it on your calculator and have it draw the graph. Notice how the "legs" point up and the extreme is at (0,0). The final answer would be to write it like this: \[f>0 \in ]\infty;0[\] \[f=0 \in [0]\] \[f<0 \in ]0;\infty[\]

Best ResponseYou've already chosen the best response.0I forgot about the interval... remember it's not \[\infty\] but 8 to 8
