To determine the domain and range of the function f(x) = -2x² - 4x - 5:

Domain refers to the set of all possible input values for the function, which, in this case, is x. Since this is a quadratic function, there are no restrictions on the values of x, and thus the domain is all real numbers. Therefore, the correct option for the domain is C: Domain: All real numbers.

To find the range, we can consider the leading coefficient of the quadratic function. Since the leading coefficient is negative (-2), the parabola opens downward. This means that the vertex of the parabola represents the maximum point, and the range will be all real numbers less ...
