The domain of the definition of the function f(x)= 1 4-x^2 + ₁₀ (x^3-x ) is

Options

  1. A(-1,0) (1,2) (3, )
  2. B(-1,0) (1,2) (2, )
  3. C(-2,-1) (-1,0) (2, )
  4. D(1,2) (2, )

Correct answer

B. (-1,0) (1,2) (2, )

Step-by-step solution

f(x)= 1 4-x^2 + ₁₀ (x^3-x ) to define f(x) 4-x^2 0 and x^3-x>0 x^2 4 and x(x-1)(x+1)>0 x 2 and x (-1,0) (1,2) (2, )
