I learned in the earlier chapters that peaks and valleys of a fxn have points where f'=0 (i marked them with red x). A few chapters later it said if a fxn has 2 roots, then f'=0 (still the 1st graph).
So does that mean if the graph of a fxn is like the 2nd graph, the peaks and valleys are not f'=0? I drew where i would assume f'=0 with blue circles
