The function given is f(x) = -2 x (x - 1) (x - 2). To find f(1), substitute x = 1 into the expression.

f(1) = -2 × 1 × (1 - 1) × (1 - 2).
Since (1 - 1) = 0, the entire product becomes 0, regardless of the other factors. Therefore f(1) evaluates to 0.

A quick check of the domain: this is a polynomial, which is defined for all real numbers (and complex numbers as well). There is no division by zero or square root of a negative number involved, so no undefined or complex issues arise here.

Thus, the computed value is obtained directly from the zero factor without needing further consideration of undefined cases.
