Answer:
Let's complete the square first.
y = x² + 6x + 3
= (x² + 6x + 9) - 6
= (x + 3)² - 6
Therefore, the vertex is (-3, -6) and since the coefficient of (x + 3)² is positive, the vertex is a minimum.
The result of the product of (0.36) and (0.53) is 0.1908
<h3>How to determine the product</h3>
The product expression is given as:
(0.36) * (0.53)
Rewrite the product as follows:

Expand the product
