differentiation

[fathom cave]

It has to be between the two turning points to be able to have 3 roots

Q and R is what I’m referring to

K as to be between the y values of Q and R

This is what I mean

No

The answer should be
K=10 k=5

Yh

Idk what Ure doing but sure maybe it works

Sorry I didn’t even read the q properly

U could just do this tho

And just find the answer straight away
