The statement that best describes the error in the graph of the quadratic function f(x) = -(x + 2)² - 1 is given by:
The vertex should be a maximum.
What is the equation of a parabola given it’s vertex?
The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient. If a is negative, the vertex is a maximum, and if it is positive, it is a minimum.
In this problem, we have that a = -1 < 0, hence the vertex should be a maximum, which means that the correct option is:
The vertex should be a maximum.
