Question 42: Given a definite function y=f(x) that is continuous on \(\mathbb{R}\) and has the following variation table Which of the following statements is true?

Based on the variation table we have:

f(x) covariates on \(f'(x)>0\forall x\in (-1;0)\cup(1;+\infty)\) so the function is covariant on the intervals (-1,0) and \((1;+\infty)\)

The function peaks at x=0, \(y_{CD}=3\)

The function has a minimum at \(x=-1\) and \(x=1\), \(y_{CT}=-2\)
