So the function is [tex]f(x) = 2 + 3x^{2} - x^{4}[/tex]
Find the intervals of increase + decrease, local max + min value, inflection points (IP), interval the function is concave up + down
I know that I need to first find f'(x) to find the increase and decrease, so I solved that:
[tex]f'(x) = 6x - 4x^{3}[/tex]
Now, the problem I'm having is finding the critical numbers. I know that 0 is obviously one of them, but I don't know what the other one is (since I'm quite confident that there is another one)
Thanks for your help!
