Question

The graph of y = x2 is shown below. Using complete sentences, explain how the graph
of y = –2(x + 3)2 + 1 would differ from this parabola.

Answer 1

Define X=x-3;
so y=-2X^2 + 1
so because of X=x-3 the original parabola will shift 3 point to left
and because of -2 factor , it will flip and twice in size , and because of +1
it will go up 1 point .
