Consider the graph of the quadratic function y = 2(x + 3)2 β 3 with two real zeros. What number can be added to the right side of the equation to change it to a function with one real zero?.
Accepted Solution
A:
Making the outside constant on the right be zero will shift the function so the vertex is on the x-axis. At that point, there is only one real zero.To make that happen, 3 must be added to the -3 that is there.
