(1 point) Consider the function f(x)=-2x^(3)+45x^(2)-300x+8. This function has two critical numbers A=B=f^(')(x)(-infty ,A):
(A,B):
(B,infty ):f(x)ABA :
A=
and B=
For each of the following intervals, tell whether f^(')(x) is positive (type in + ) or negative (type in -).
(-infty ,A):
(A,B):
(B,infty ):
Thus f(x) has a relative
at A (type in MAX or MIN)
and a relative
at B (type in MAX or MIN).
(1 point) Consider the function f(x) = --2x3 + 45x2 -- 300x + 8. This function has two critical numbers A < B: A=
and B= For each of the following intervals, tell whether f' (x) is positive (type in +) or negative (type in --). (co,A):
(A,B): (B,0o): Thus f(x) has a relative
at A (type in MAX or MIN)
and a relative
at B (type in MAX or MIN)
