Question 41: Given the function \(y = f\left( x \right)\) has the following table of variation: The function reaches its maximum at the point

Based on the variable table, we have the function \(y = f\left( x \right)\) which peaks at the point x = 0.

+ The maximum value of the function is 1 and the function has no minimum value on \(\mathbb{R}\) so B is wrong.
