Consider the graph of the quadratic function y = –2(x + 2)2 – 1 with no real zeros.
What number can be added to the right side of the equation to change it to a function with one real root?

Add 1.
Reason: the vertex is at y = -1. Adding 1 raises the vertex to y = 0, giving y = -2(x+2)^2, which has the single (double) root x = -2.
