Answer 2

@.Sam.

Answer 3

Thank you for helping my question get attention @chpatterson

Answer 4

No problem

Answer 5

@steve816 you said that `I am allowed to use a calculator` so I'd definitely take advantage. Doing this by hand would be a pain.

Rule: The local extrema of `f ' (x)` correspond to the points of inflection on `f(x)`

Use your calculator to find the approximate extrema (local min and max) of `f ' (x)`

Answer 6

If your teacher won't let you do that, then you'll have to use the product and quotient rule

Answer 7

its similar behavior to that function

Answer 8

like 8 or 9

Answer 9

x^2 cos^2(x) has the same inflection points as cos^2(x)
