If `f(x) =x^4-8x^3+4x^2+4x+39 and f (3 + 2i) = a + ib` then `a : b` is equal to

If f(x) =x^4-8x^3+4x^2+4x+ 39 and f(3-2i) =a+ib, then the vaue of a.b is

If 2f(x) + 3f(-x) =15 -4x, then f(x) is equal to-

If f(x)=x^(3)+2x^(2)+3x+4 and g(x) is the inverse of f(x) then g'(4) is equal to a.(1)/(4) b.0 c.(1)/(3) d.4

If f(x)=x^(3)+2x^(2)+3x+4 and g(x) is the inverse of f(x) then g'(4) is equal to- (1)/(4)(b)0 (c) (1)/(3)(d)4

If (d/dx)f(x) = 4x^3 - 3/(x^4) such that f(2) = 0 . Then f(x) is

If g(x) = 2x^(2) + 3x - 4 and g (f(x)) = 8x^(2) + 14 x + 1 then f (2) =

If g(x) = 2x^(2) + 3x - 4 and g (f(x)) = 8x^(2) + 14 x + 1 then f (2) =
