Parabola equation:
The equation of a parabola has the following format:
![y = ax^2 + bx + c](https://tex.z-dn.net/?f=y%20%3D%20ax%5E2%20%2B%20bx%20%2B%20c)
If
, that is, x² is multiplied by a positive number, the function has a minimum value and the parabola opens up.
If
, that is, x² is multiplied by a negative number, the function has a maximum value and the parabola opens down.
In this question:
![y = -x^2 - 2x + 3](https://tex.z-dn.net/?f=y%20%3D%20-x%5E2%20-%202x%20%2B%203)
From the graph, we already see that it opens down and has a max, and analitically, since
, this is confirmed. The correct answer is given by option b.
