Explanation:</h2>
The vertex form of the equation of a parabola is given by the following form:

In this exercise, we have the following equation:

From here, we can conclude that:

Since the leading coefficient is less than zero, the parabola open downward. So, the graph is shown below and the vertex has been indicated.

Step-by-step explanation:
The quotient is -16.4

Apply the fraction rule:

Divide the numbers: 

The quotient rule is a calculus technique for determining the derivative or differentiation of a function that is represented as a division or ratio of two differentiable functions.
Therefore, we can apply the quotient method to get the derivative of a function of the form f(x)/g(x), where f(x) and g(x) are both differentiable functions and g(x) ≠ 0. The quotient rule immediately follows the product rule and the notion of limits of derivation in differentiation.
