Answer 1

Am i correct?

Answer 2

I don't think you're correct.

Often the easiest way to identify these is to look at the general equation for each.

A looks like a quadratic, B a cubic, and C a quartic.

Answer 3

But that doesn't seem to work here. I can't find a good option.

A cannot be f, because neither B or C have a zero that corresponds with where A has a horizontal tangent

C cannot be f, because at several points where C has a horiz. tangent, the other two don't have zeroes corresponding with it.

Answer 4

yes, it should be C,B,A
but the actual shapes don't make sense.

Answer 5

Yes, honestly nothing works here.

The last option i have is B is f, A f', C f'', but that doesn't work since C cannot possibly be the derivative of A.

Answer 6

Option A is incorrect.

B is incorrect.

C is close-ish but incorrect.

D is incorrect.
