Do Not use any de cimals for approximation and or arithmetic. Use fractions when appropriate, Not decimals Q4c is a critical point for a function f, then f must have a local maximum value at C, a local minimum value at C, or an in flection point at (c,f(c)). bc is in the Domain of a function f, and f^('')(x)<0 for all f^('')(x)>0x>c(c,f,(c))fgc,dggc,dx, and f^('')(x)>0 for all x>c, then (c,f,(c)) must be and inflection pain of the graph of f. c
