Question 214872: y = - |x + 3| how do I find the vertex and does the graph open upwards or downwards?

The graph opens downward because there is a minus in front of the absolute value sign.
-----
The vertex of the graph will be at x = -3 because that is the value of x when y = 0

a graph of this equation looks like this:
