f(x)=4x-(1)/(2)x^(2),x in[-2,(9)/(2)]

Find the absolute maximum value and the absolute minimum value of the following functions in the given intervals: f(x) = 4x-1/2x^2, x in [-2,9/2]

Find the absoloute extremum of f(x) = 4x - (x^(2))/(2) on [-2, (9)/(2)] .

Find the absolute extreme of f(x)=4x-x^2/2" on "[-2,9/2]

If f(x)=(4cos^(4)x-2cos^(2)x-(1)/(2)cos4x+2sin^(2)x-x^(9))^((1)/(9)) then the value of f(f(2)) is equal to

Let f (x) =(1)/(x ^(2)) int _(4)^(x) (4t ^(2) -2 f '(t) dt, find 9f'(4)

Let f (x) =(1)/(x ^(2)) int _(4)^(x) (4t ^(2) -2 f '(t) dt, find 9f'(4)

If f(x)=(1)/(x^(2)+4x+4)-(4)/(x^(4)+4x^(3)+4x^(2))+(4)/(x^(3)+2x^(2)) the f (1/2) is equal to

Let f(x)=|(1,x,x^(2)),(x,x^(2),1),(x^(2),1,x)| then |f(2.9)^(1//3)|= ___________
