Let f(x)=x2−4x+c∀x∈Rf(x) = x^2 - 4x + c \forall x \in R, where cc is a real constant, then which of the following is/are true ?

Options

  1. Af(0)>f(1)>f(2)f(0) > f(1) > f(2)
  2. Bf(2)>f(3)>f(4)f(2) > f(3) > f(4)
  3. Cf(1)<f(4)<f(−1)f(1) < f(4) < f(-1)
  4. Df(0)=f(4)>f(3)f(0) = f(4) > f(3).

Correct answer

A. f(0)>f(1)>f(2)f(0) > f(1) > f(2)
