Find the points of local maxima or local minima and corresponding local maximum and local minimum values of each of the following functions.Also,find the points of inflection,if any: f(x)=x^(4)-62x^(2)+120x+9

Find the intervals in which f(x)=5x^(3)-15x^(2)-120x+3 is increasing or decreasing.

Find the points of local maxima or minima and corresponding local maximum and minimum values of f(x)=x^4-62 x^2+120 x+9 . Also, find the points of inflection, if any:

If f(x)= 3x^(4)- 5x^(2) + 9 then find f(x-1) .

If f (x) =3x ^(9) -2x ^(4) +2x ^(3)-3x ^(2) +x+ cosx +5 and g (x) =f ^(-1) (x), then the value of g'(6) equals:

If f (x) =3x ^(9) -2x ^(4) +2x ^(3)-3x ^(2) +x+ cos +5 and g (x) =f ^(-1) (x), then the value of g'(6) equals:
