Put and solve the quadratic.
I'm having trouble finding the point of inflection of the graph
so I cannot find the points of inflection even though I know the procedure:
f''(x)= 0 and f''(x) = undefined both do not exist...soo there is no point of inflection right? no.. there has to be BECAUSE, when i graph the function, concavity is changing.
from (-infinity, ln2) we have concave up and from (infinity,ln2) concave down. now... how do i find the point of inflection if i know that concavity is changing, but the second derivative does not allow me to find the point?
max point (ln2,2)
