Consider the function f(x)=-2x^(3)+30x^(2)-54x+7. 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 local at A (type in MAX or MIN)
and a local at B (type in MAX or MIN).
Consider the function f=23+30254x+7.This function has two critical numbersA<B: A= andB= For each of the following intervals, tell whether f'() is positive (type in+) or negative (type in -) -A A,B B,00) Thus f()has a local at A(type in MAX or MIN) and a local at B(type in MAX or MIN)
