Question

determining key aspects of a quadratic function
the graph of the function f(x) = -(x + 1)² is shown. use the drop - down menus to describe the key aspects of the function.
the vertex is the maximum value.
the function is positive drop - down menu.
the function is decreasing drop - down menu with options: when x < -1, when x > -1, for all real numbers of x, for no values of x
the domain of the fu incomplete
the range of the fun incomplete

Explanation:

Answer:

The function is positive: for no values of x
The function is decreasing: when x > -1
The domain of the function: for all real numbers of x
The range of the function: $y \leq 0$
