The function f(x) = -x² represents a quadratic function, which is a U-shaped curve that opens downward due to the negative coefficient in front of the x^2 term.

The domain of this function refers to all possible input values of x for which the function is defined. There are no restrictions or limitations on the input values x. Therefore, the domain of f(x) = -x² is (-∞, ∞), which includes all real numbers.

The range of a function repre...
