I am suppose to derive the following and then find x if f´(x)= 0
f(x) = (6-x2) [tex]\bullet[/tex] e2x
Which one should be used? I guess I am confused with the fact that it is e2x
Product rule gives:
(6-x2) [tex]\bullet[/tex] e2x + e2x [tex]\bullet[/tex] (-2x)
e2x(6-x2-2x) (x1 = 0)
-x2-2x+6 = 0 gives decimal values that doesn't seem to fit.
Chain rule gives:
I'm not even sure how to start here. I assume that the outer derivate is e2x? Or should the chain rule be applied to it and then the product rule?
Some kind of hint as to what is the correct path would be greatly appreciated
