Explanation The root of any function f ( x ) is defined as the input x , where the value of the function is equal to zero. Given: A function as f ( x ) = x e − x Calculation: Given that the function is f ( x ) = x e − x x f ( x ) = x e − x - 2 f ( − 2 ) = (-2) e − 2 = − 2 e 2 = - 0 .2706 -1 f ( − 1 ) = (-1) e − 1 = − 1 e 1 = - 0 ...
