The function f(x) = x² represents a quadratic function, which is a U-shaped curve that opens upward.

The domain of this function refers to all possible input values of x for which the function is defined. Since the square of any real number is always non-negative, there are no restrictions on the input values. Therefore, the domain of f(x) = x² is (-∞, ∞), which includes all real numbers.

The range of a function represents all possible output values that the function can attain. For this quadratic function, the range is [0, ∞). This means that the funct...
