f(x) = (x^3 3x^2 + 5) = (x^3) (3x^2) + (5) = 3 * x^(3 1) 3 * 2 * x^(2 - 1) 0 = 3 * x^2 6 * x^1 = 3x^2 6x.

f(x) = ((x^2 + 1) / (x^2 1)) = ((x^2 + 1) * (x^2 1) - (x^2 + 1) * (x^2 1)) / (x^2 1)^2 =

f(x) = (-x) = (-1 * x) = (-1) * (x) = (-1) * (1 / 2x) = -1 / 2x.

f(x) = ((x^3 + 1)^4) = (x^3 + 1) * ((x^3 + 1)^4) = ((x^3) + (1)) * ((x^3 + 1)^4) = (3x^2 + 0) * 4 * (x^3 + 1)^3 = 12x^2 * (x^3 + 1)^3.

f(x) = (2 * (5x + 4)^(-1)) = 2 * (5x + 4) * (5x + 4)^(-1) = 2 * ((5x) + (4)) * (5x + 4)^(-1) = 2 * (5 + 0) * (-1) * (5x + 4)^(-2) = -10 * (5x + 4)^(-2) = -10 / (5x + 4)^2.

f(x) = ((-4x^3 + 1)^4 - (2 - x)^5) = ((-4x^3 + 1)^4) ((2 - x)^5)) = ((-4x^3 + 1) * (-4x^3 + 1)^4) (2 - x) * ((2 - x)^5)) = ((-4x^3) + (1)) * (-4x^3 + 1)^4) ((2) (x)) * ((2 - x)^5)) = (-4 * 3 * x^2 + 0) * 4 * (-4x^3 + 1)^3 (0 1) * 5 * (2 x)^4 = -24x^2 * (-4x^3 + 1)^3 + 5 * (2 x)^4.
